DIY Multitouch Interface

We talked about multitouch screens today in class, and I remembered this video from a while back.



Maybe it'd be cool to make. It doesn't seem all that complicated. I'll need to look into Core Video some more, but I think it would make the kind of video processing needed pretty straightforward.

It's not a screen, it's just a control surface, so it wouldn't be practical for a lot of the things we were talking about in class. Actually, it's a bag of water on a glass table with a camera underneath. I can't imagine it being practical for anything.

But, it's cool looking, and it's a neat idea.
