We did this little show three times over three successive nights, to an audience of several thousand of the brightest minds in the computer graphics world. As far as I could tell, they didn't get it. Well, that live stuff has no practical value, but it's a great stunt. We did a few more live performances - the keynote address at the TED 2 conference, for example. And they both still do that impractical, useless live animation stuff.
Some people never learn.
