I was never the one who had to draw all the time, and although I do go through phases of drawing more, I'd have to say no. I think I prefer the theory to the actual practice!

As for people painting the Sistine Chapel on phones, well some people manage to get good results even from Microsoft Paint, or the humble Etch-a-sketch... that would be people with far too much time on their hands if you ask me!

I did see a video of someone doing a really cool piece on an ipad, and now I wish I'd kept the link to sift (although it might be here already).In reply to this comment by taranimator:
Digital finger painting is strangely both more liberating and more restrictive. I'm still messing about with about 5 different apps trying to find one I could call 'user friendly'. On my home computer I have a lovely Cintiq -- you can see the image and draw on it with a stylus. I quite dig that. On my phone and my Ipad I can draw with my finger or a stylus. The finger painting is more awkward in some ways but to get the ipad/pod to pick up the motions of the stylus you have to press really hard! It's a bit weird. There's no real touch-sensitivity like on the Cintiq -- various apps try to simulate the look of it with tapering and speed = line width contols. So far not so good for me. But OTHER people are painting the freaking Sistine Chapel on their phones.. so the problem is probably not the tools but the user, ahem - me!
Still, I persevere! I swear, had I never seen the beautiful artwork people make on their phones, I never would have considered it possible. But I am intrigued.. and it IS fast! I can then upload those sketches to polish in a proper graphic program or just enjoy their speed-painting loosensess.
Are you a doodler?

Well that sounds like fun Speculating wildly, since I totally lack the experience for an informed comment, I would expect that the ipad might be a little like water colour painting, in that a looser approach and taking what you get might work well but if you try to get every pixel exactly right you would be better off with another medium... and also that a few stray splotches or rough edges might not hurt the final product. Do you use a big touch pad on your main computer?

As for what they were smoking in the 70s, well in my parts it was only a few extremely mellow hippies in the hills, smoking so much weed that they hadn't realised the 60s were over In terms of animation though, I wonder if the 70s were the result of digesting the trippy LSD inspired experiments of the 60s and reacting to them, without perhaps actually being chemically enhanced. I wasn't yet 10 when the 70s ended though, so it's yet more wild speculation on my part.

@arvana. I think some important questions are: Is the pipe perpendicular to the sea floor and straight? How long is it to the end of the pipe?

It would be informative to calculate the force on the plug as a function of separation.

In a nonuniform hydrodynamic flow your cone will be unstable. Rifling, could help... and may only be necessary on the initial part of the taper.

@jimnms: Having a pipe running through the plug is a great idea -- then they can stay in production, which I agree with @MaxWilder is BP's main goal.

@xxovercastxx: An inflatable plug is another excellent idea, the tricky part will be securing it before inflation so it can withstand the upward pressure of oil as it seals against the pipe, otherwise it will get blown out. It could also just be made heavy enough to overcome the pressure.

@MycroftHomlz: The taper length is definitely relevant, but unless the blowout preventer itself has some inner geometries that prevent a long taper, there is nothing stopping it from being as long as possible. The horizontal pipe on the sea bed has been cut off.

OK. So I see the confusion. Let me explain.

If you have horizontal pipe on a sea bed with a pipe leading to the surface, then you can think of the pipe as a sideways laying "L" like this ____|. The stub that goes to the surface is some distance 'x' long. So the maximum length you can make you taper, until the diameter is equal to the diameter of the pipe is some length less than 'x', the length of the stub.

Does that make more sense?

This means there is a limited length you can make the taper. Experimentally, the force needed to cap the pipe will increase with "increasing taper angle". If you think of the limiting case where the taper angle goes to 180 degrees, then there is no taper. So the point that the taper length is limited is very relevant.

I think that is clear.

>> ^arvana:

The pipe has now been cut so it's vertical at the top of the blowout preventer.

Isn't the leak essentially on the side of a horizontal pipe? So you would have a maximum length that you could make the taper. I don't think they will be able to do anything thing unless they relieve some of the flow coming from the pipe.

>> ^TreacleMine:

The debris is still there, it's just zoomed out and not on fire anymore. Look on the left side after the shake, just over the house. You can see a few black objects still falling.


Ya, you have to remember where they debris was before the cut away. Right as it cuts away, it is nearly at the same level as the upward moving shroom. We come back so you would expect the shroom to still be going upward and debris still moving downward but it has panned out so much it is hardly visible...but you can see it below (way below) the shroom after it tapers off a bit.

It's looking more and more like vietnam, isn't it? The american occupying force ought to get the hell out of there.
quality, not that the video really needs it.

All of the wars since Vietnam have been just like Vietnam. But no one seems to give a shit in the US, and if they do they sure as hell don't fucking act like it.



This is not true. It took years for significant protests of the Vietnam War to make any sort of impact on the situation in the United States or in Indochina. Before there were significant protests Indochina was bombed into oblivion with tons upon tons of war crimes mounting up, millions of people killed land deforested and people rounded up into camps. Although this horrible shocking footage is damning it doesn't compare to the monstrous brutality and murder on a mass scale that Vietnam was.

People do care, Iraq is the first War America has had that had organized large scale resistance before the War was even declared. It's tapered off due to complacency the outstanding work of the media to push it to the side so successfully and the overall Failure of the Left in this country to keep organizing people and bring about a dedicated resistance. Not having a draft and keeping the numbers there as low as possible has helped the media do it's job and point out that this isn't our problem.

It's not hard to start a resistance against this War...the groups exist and the people are out there. If you don't want to see anymore stuff like this either keep watching Lost or stand up together because this all happens in our name.

Thanks Lann, that's just the kind of answer I was looking for. I didn't even think about schools. But Fine Arts makes a lot of sense.

In reply to this comment by Lann:
No actually this is at my school. They have a Fine Arts program in Metals that ranges from coppersmithing, silversmithing to blacksmithing. Blacksmithing has used machinery like this since the industrial revolution and some of the old anvils, tools and machines are still used today. Blacksmithing today is mainly for architecture (gates ect.) and sculpture (some sculpture programs use blacksmithing equiptment)...I hope this provided some information.

In reply to this comment by Stormsinger:
I actually didn't know that anyone was still manually blacksmithing (maybe semi-manual, or manual-assisted?)...except for those few fanatics/purists/hobbyists you find at renn fests. Is this a full-time job (I'd assume so, given that piece of machinery), or more of a hobby, @Lann?

Either way, it's a fascinating glimpse at an activity I am/was completely clueless about.
