TARSplay

Payback says...

It was just over-hyped. They should have talked about the scientific accuracies after it opened. If they hadn't built it up, people wouldn't be hacking it down.

...and the robots aren't just two slabs of metal. They Rubik's Cube out, and the smaller blocks swivel out into arms and manipulators.

There's a making of TARS and CASE video on the sift (try 2:00 if you're impatient) that explains why they're a cool idea. If for nothing else, the fact they aren't anthropomorphic in any real way.

Okay... I didn't see the movie, but, I have to say those are the worst looking Science Fiction robots ever.

There have been some bad ones in the past. K-9 anyone?

But god, those are just two blocks of metal. How is that thing even supposed to balance?

Dumb, dumb, dumb.

But from what I gather that pretty much sums up the whole movie.

Virtual reality, explained with some trippy optical illusion

I like how he points out that the color "illusions" are not actually a brain failure, but an amazing visual processing feature honed by evolution. If the rubix cube were a real object photographed in yellow light and then in blue light, those tiles would have to be yellow and blue (not grey). It's like our brains calculate the true color under white light, and that's what we see.

Just think about how useful that is, without that feature we could never build up knowledge about what color different plants and animals are, because their color would seem to change drastically with the lighting conditions.

? I'm confused. I admitted my 'test' was lacking, and deferred to @ChaosEngine who didn't trust his eyes but measured...so I am no longer certain it's 'fake' at all, in fact I was careful to NEVER call it 'fake'. Perhaps you only read my first post in this thread and missed my admission that I was wrong?

As I said, I think there's a reason it LOOKED like it did to me...probably the surrounding color reflecting off the white paper I used to mask off and 'coloring' the grey squares....and likely the paper I used was not perfectly straight to use as a straight edge....and measuring anything on a screen is less than perfect, which is why I poorly measured the table and lines...the second time I measured it I did better, and I admit they are the same size contrary to my original statement.
I also only saw grey pills.

The reason I was skeptical is I've seen these same 'illusions' faked many times. For instance, the last time I saw the Rubik's cube, the tiles had dark shaded colored edges they removed when 'masking off' which obviously changed the color. It's not that I don't 'believe' in optical illusions, I just think people are cheaters more often than not these days and fudge things they don't need to fudge. This time it was my method of 'masking off' that seems to be my issue...I don't have an image editor that will do much for me here....sadly...but it doesn't mean I don't trust Chaosengine who did and set me straight.
OK? ;-)

@newtboy - I'm blown away at how certain you are it's all fake. I suggest you do what I did: Instead of using paper on your screen, just take a screenshot and insert into an image editor and inspect things there.

I cut the three tiles out and pasted them side-by-side and they are in fact the same color: http://i.imgur.com/e5lcV5P.png

I dragged straight lines on the checkerboard before and after the dots were added, and it has only straight lines.

I copied/pasted the blue tabletop, rotated it and it fit perfectly on the other one: http://i.imgur.com/QzT8nc8.png

Nothing was fudged in the video. It just shows how powerfully your brain is latching onto what it believes it is seeing.

It's like that dress photo from a few weeks ago. "Is it white and gold or purple and black?!" Many people were hardcore in one direction or the other.

The only one that left me confused is the pills. 1) He said they were red and blue, but they were yellow and turquoise. 2) They had holes in the pills allowing the background color through; it was only there that they looked colored, otherwise they were just gray. I suspect they were just trying to shoe-horn in a red pill blue pill Matrix reference.

You went farther than I did then.
All I can say is when I cut out squares in a piece of paper, I could see a difference until they 'masked off' the image, then it had changed. I know these can work without fudging, which is why I was disappointed.
Did you note the difference between the 'colored' image and the 'masked off' image? It sure seems like there's a difference to me, if I stop it 1/2 way through and cover all but 2 squares, one is slightly lighter than the other on my monitor. That went for both the cubes and the floor tiles. Maybe it's 'eye memory' or something, but it sure seemed to me that the center tile was noticeably lighter until the 'masking off' happened.
I used a piece of paper against my monitor to measure the table,....I must have moved it when marking it, because now when I do it, it seems the tables ARE the same size. Damn touch screen, kept starting the video every time I touched it.
If those lines were really pixel straight, my paper is cut with a curve or my monitor has a problem.
Again, you went farther than I did to prove it, so I'll defer to you and accept I'm seeing things, even when I mask them off myself.

EDIT: Just a thought why I may have seen it differently, do you think it's possible that 'light bleed' or 'color bleed' on my monitor has anything to do with it? I mean, since the pixel next to the 'grey' block might be glowing bright yellow, it could color the grey slightly yellow, while the RGB value would not change?

ChaosEngine said:

Sorry, newt, but that's simply inaccurate.

I saw two grey pills too, but you're completely wrong about the others. I screen shotted all the images into paint.net to verify them.

The rubix cube image is 100% real. The RGB values for the blue and yellow tiles are identical (127,128,129).

Same with the the tiles under the table. They are are off by a small amount (rgb 70 68 71 vs rgb 70 68 70), but I'd but that down to the video encoding.

Ditto with the checkboard; zooming in with paint.net the lines are pixel straight (there is some anti-aliasing at the edges, but it doesn't affect the "straightness of the checkerboard").

The tables too, are the same size. I rotated the vertical table.

If you don't believe me, try it yourself.

OK. Looking extremely closely and using paper to block out the image, I have to say they fudged things on some of them.
I saw two grey pills the whole time.
The colored tiles fade to grey as they "mask off" the other tiles, they start no where near the shade of grey they end up as, their color has faded a lot in the process.
The grey tiles on the floor also change shades as they are 'masked off' quite clearly. I went 1/4 speed, and also tried masking them off myself, they clearly faked this one.
I put a straight edge on the checker board and sure enough, those lines are slightly curved....just barely but they are.
The two table tops are NOT the same size at first, I measured and the vertical table is definitely longer on the long side. That one's obvious.
The spinning dots does work for me, as do convex images and auditory illusions.
So I'm not ready to call 'fake' on this, but IMO it's fudged badly.

In the first image I saw both as matching grey pills the whole time - neither looks even slightly tinted to me. Is anyone else getting that? I have no color blindness at all and the cube illusion works just fine. Weird.

In the old VS, a message would pop up like "Great, you've started voting! Now sign up to make your votes count!" but I believe that doesn't happen anymore.

Holy S**T, This Woman Can Rap!!

ChaosEngine says...

someone over 30 rapping? Not even vaguely unusual. Dre, Snoop, Chuck D, Ice Cube... these guys are over 40.

But a middle aged blonde english woman rapping? Yeah, that's something you don't see everyday.

I'm 46. My generation popularized rap. Why is someone over 30 rapping impressive? Rap is old enough that "old school" is actually old.

Cities: Skylines Review (What SimCity should have been!)

What colors do YOU see?

newtboy says...

It always looked clearly black and blue to me, no matter which screen I see it on. How could that color be white?
I don't get the explanation. It seemed he was saying some people think if there's a blue sky or surroundings, that anything white will reflect that and look blue?! WHAT? I've never once thought a white T shirt looked blue outside or in a blue room. That sounds crazy to me. I note that another clear shot of it at the end was just as close up and with nothing to compare the colors to, but is obviously black and blue. Doesn't that blow their explanation right there?
EDIT: Also, there is white right next to the dress in multiple places. Can people really not see a difference between the dress and the white wall/window?

Also, looking closely in the cube example, the lower brown square IS slightly lighter in color than the top one, even when they remove all other squares. Also, they DID cheat, just look at the edges of the squares (when in the cube). They are also shaded to darken the upper square and lighten the lower one. They remove the edges when they show just the two squares, actually changing the overall colors. That's totally cheating....so they're totally liars! ;-)

Flow Hive - Honey directly on tap from your beehive

BicycleRepairMan says...

By the way, this kickstarter is going fast! Yesterday there was about 1000 out of 5000 full $600 packages sold, today its 2000+ sold. So if you want a cube , I suggest you get going within the next 7 days.. I ordered mine yesterday. Too bad their estimated shipping is december, but I guess that gives me some time to prepare for next spring/summer!

Preservation - People Being Covered in Gallons of Honey

BicycleRepairMan says...

I suppose its a waste of good food, but buying honey is not hurting the honeybee cause, it creates demand for more honey, which means hopefully more people will start beekeeping, which will result in more bees overall. Remember, the problem isnt the lack of honey, but the lack of pollinators, ie: bees.

On a related note, I just ordered a Flow Hive cube(https://www.indiegogo.com/projects/flow-hive-honey-on-tap-directly-from-your-beehive), and cant wait to start my own beekeeping-project
