I thought is was a fun demo. If I saw that on the pier or at a festival I would definitely stop and watch. I don't see why people have to be so critical when viewing others art.
I mean I bust Handjobs ballz because he is a goob and has no compass. But if he did a demo why not watch and appreciate the performers time and energy?
Now, if after the demo he went off on vectors and played romper room with his "friend" and their special ball toy, then may be that would be the time to get back to reality.
But as stated I enjoyed it.
