Fibonacci Zoetrope 3D Printed Sculptures

eric3579 says...

From description

In person uses a strobe light to get this effect. For this video, rather than using a strobe, the camera was set to a very short shutter speed (1/4000 sec) in order to freeze the spinning sculpture.

How much of that phenomenon is a function of the shutter speed on the recording camera? Does it occur in person as well?

Amazing Water & Sound Experiment at 24Hz #2

Awesome illusion - A static flow of water

Trancecoach says...

it's an example of the stroboscopic effect -- an optical illusion whereby the stream of water is vibrating at the same frequency as the video is running (presumably 24 fps), making it seem like the water is "streaming" in a spiral, when it's only those droplets captured by the video that are vibrating with the sound to make it appear that way. It's the same reason car wheels and propellers appear to change direction as they speed up or slow down when seen on film or through a strobe light.

Still, knowing how it works doesn't make it any less cool!

Prepare to be Freaked Out by this Voice

On a side note, first song is Drowning Pool - Bodies, which was allegedly used by interrogators in Guantanamo bay, along with strobe lights. Not a hundred percent sure how recreating the typical concert could be considered a form of torture, but I'm not expert.

>> ^wormwood:

Or get a strobe light with adjustable flash rate. Then you can see this effect in real time.
I spent one evening with a bunch of friends, a strobe light and a dark, indoor swimming pool. Lotsa trippy fun. >> ^Zawash:
Brilliant - got to try this at home. Hmm - by slowly increasing the shutter speed, the water should go from flowing water to still droplets like in the video. A simple 25Hz wave should be great for recording at 25fps.



Shame. I don't imagine we're thinking of the same kind of fun that could have been had at that dark indoor swimming pool with a bunch of friends.

How does it go in spirals though? Is it normally spraying up and down, but we're just missing those frames? This is WAY cooler than any strobe light effects I've ever seen.

MIT build 1 trillion FPS camera - captures photons in motion

messenger says...

It didn't take a trillion frames in one second. It has an effective terafps framerate, but the photos were taken of different photon pulses over several minutes. It looks like a single photon pulse travelling slowly, but isn't, just like if you've ever seen the experiment with steadily dripping water and a strobe light where the water drops can be made to appear to slow down, hover in the air, and even travel back up.>> ^MonkeySpank:

I am guessing even parallel GDDR5 memory is not enough to handle the bandwidth of 1,000,000,000,000 frames. I am curious mostly about how this is information stored.

Evil Proves God's Existence

@Sagemind

Being a slave to another person is a wretched life.
Being a slave to a concept is unfathomable.
Religion is a concept of man.
Religion is a concept designed to subjugate and control a population.


Religion is a man made system that has been used for good and evil. We know God through faith alone.

There was a time when education was unheard of and only a relative few were exposed to it. Rulers kept everyone else dumb so they could be controlled. Religion was and always will be designed as a tool to control. In the beginning there were many sects and religions. As the religions caught hold, they slowly choked out as many other religions as they could to exercise their brand of control. Christianity happened to be one of the few that was more ruthless at destroying the others. (Many are documented in the bible - Genocide in the name of religion included.) The smaller religions only needed to be discredited and be called cults - as they continue to do today.

The early church was heavily persecuted by many different dictators. Believers were frequently martyred because they reufsed to worship other Gods. The expansion of the early church under these circumstances is one of the positive evidences for Gods existence as it is unlikely it could have happened in that climate of persecution. There was nothing to gain from being a Christian in those days except being an outcast.

Genocide is committed in the name of many things, and today the masses are no less controlled by secular Governments than they have been under religious ones. Bad behavior is not an exclusive to religion, it is the nature of man himself, who could corrupt anything beneficial. That people have acted badly in the name of Christianity isn't proof of anything except mans inherent corruption.

Now, many, many lifetimes later, man has become educated and has thrown the shackles of religion (a form of slavery) and science has emerged as we seek for fact instead of fiction. There are many who are still bound to religion and can't function without the masters hand to lead them. They have lost, it seems, the ability to reason, with cognitive thinking, on their own.

Many need the presence of a deity to explain the un-explainable. It's a neat fully-packaged explanation that never needs unwrapping. It is easy. It's man's nature to pick the easy route. To many it just makes more sense. To others, those more cerebral, they want to see what is underneath. They refuse to accept what is fed to them and dig a little deeper. What they find is a world of control and dominance but also a world of wonder where education can lead one on many journeys.


The question of whether the Universe is random or deliberately created is not only credible, but utterly necessary and fundemental to understanding who man is and how he relates to the Universe. Perhaps you should try Contrary to popular belief, intelligent design is a scientific theory which seeks to explain the Universe just as evolution does. The question of God is central to philosophy and our most noted philosophers have debated this question of Gods existence throughout recorded history. The complexity of life is inadequately explained by materialistic processes, and many of these theories, such as evolution, are metaphysical to begin with.

There is a percentage of the population that operates on the right side of the brain where zeros and one are absolutes and in-fact they are. They work on a puzzle where the pieces are scattered everywhere in a dark room. The pieces don't always fit perfectly so someone else pulls them apart and the big picture is corrected. Every once in a while a strobe light goes on and larger mistake is noticed and we go back to restructuring out truths.

Religion want's to turn out the lights forever, kick everyone out of the room and continue to control those free thinkers. Individuals with original thoughts scares religion. The control will crumble and individuality will rein. Their fear is that without the control, chaos will ensue. What they don't see is that to stifle education is to bring about that which they fear most.


The most basic and fundemental questions of life have not been advanced one iota. There is a higher truth operating here: Man advances theories of life which convenience his own personal hypocripsy and enable him to do evil without consequence. This is a basic truth:

John 3:20

This is the verdict: Light has come into the world, but men loved darkness instead of light because their deeds were evil.

Everyone who does evil hates the light, and will not come into the light for fear that his deeds will be exposed.

But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God."

1 Corinthians 2:14

“The natural (unredeemed) man receiveth not the things of the (holy) Spirit of God: for they are foolishness unto him: neither can he know them, because they are spiritually discerned”.

1 Corinthians 3:19

For the wisdom of this world is foolishness with God. For it is written, He taketh the wise in their own craftiness.

I still am not sure which they fear most. Is it the chaos itself, because look around, it exists with or without religion and often because of religion. Or is it the fear of loosing out on the promise of a Utopian forever. A mythical heaven where every single person has a different definition of. A place of fantasy.

Religion works on some of you. You remain a cow in this life so that you can experience a better life later. Well, heads up people, This is the life and you've been duped. Religion has brain washed you to do it's bidding. You fight the good fight for what you've been told is true by a hierarchy of rulers who seek the top roles in dominance. This isn't just true in Christianity, it goes for all religions. You are the pawns, the people on the front lines, leading the way, taking the brunt of accusation while the leaders at the top live the good live. You send your money (tithes) to them while you scrape to live a decent life.


I neither came to Christianity out of fear, or because I desired another life over this one. Nor was I indoctrinated or persuaded. Rather I was instructed in the spirit, and received personal revelation of the truth. I came to it independently and my convinctions rest solely on that. Your belief about an interdepedence due to a weakness of mind or character is wholly invalid.

I for one will not erase myself to the "Greater Good" of a hierarchy that cares more about it's well being/proliferation than it cares for the individual thought of a free thinking individual. It is my nature to put my thoughts and opinions before those of a mindless juggernaut that is religion. I will not allow my free thought to be controlled, twisted or stifled by anyone or anything.

Anyone with self respect should feel the same. Giving up on reality and calling it faith is really just saying, "Wow, that's just to much to take in and comprehend, I'm just going to shut down now. I will never have to concern myself with trying to keep all the balls in the air anymore. I will let a God sit in the driver's seat and ride out the rest of my life as a passenger." On top of that you spend all your days yelling out the window that you've got it so easy, you don't have to drive, you'll get to enjoy things when you get to your destination. What you fail to see is the person in the driver's seat doesn't have a license to drive, or a body or anything, they are plain fiction and the end of the road is a brick wall. When will you look up and see that you should have taken the wheel and honored the privilege of the ride before it was too late.


This imagined heirarchy of yours is a convenient strawman for your arguments about personal freedom, but it doesn't bear out. There is no conspiracy here. The body of Christ is so fractured at this time that a belief there is a heirarchy of control is simply ludicrous. Belief in God is about personal conviction and personal responsibility. Convinction because we are all sinners who have transgressed Gods laws. Responsibility because God is the moral authority who judicates our lives. You seem to think you're free, but anyone who sins is a slave to sin. You seem to think you're without a god, but you have something you worship. Whether its something in the world, or in the case of many secular humanists, yourself, there is something out there that you bow down and kiss every day of your life. Your freedom is just another box that you feel comfortable in. There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy.

1 Corinthians 13:11-13

When I was a child, I used to speak like a child, think like a child, reason like a child; when I became a man, I did away with childish things. For now we see in a mirror dimly, but then face to face; now I know in part, but then I will know fully just as I also have been fully known. But now faith, hope, love, abide these three; but the greatest of these is love.

Compressed Bondage (Blog Entry by youdiejoe)

rougy says...

You know, Joe?

I used to envy you, but now I pity the fact that you had to spend so many hours in a dark room filled with degenerates. Yes, pity. You could have told them to put on their clothes...but you didn't. You could have told them that their genital piercings interfered with you strobe lights. But instead you pretended to be a shadow on the wall, a mere fleck of reflection with a bitching camera and a damn good eye.

(did the...did the...did the hot lights make the girls smell like perfume?)

Okay! That's enough!

Just know that somewhere, someplace, some poetic weirdo envies your existence.
