I was just messing around, seeing what I could do with this shape transform effect in Flash. It's decent, but kinda limiting.
The hands are done using actionscript, and if you watch closely the big hand responds energetically when it touches the little blue ball (not the big one that gets dropped). This was my failed attempt at complicated interaction between the balls and hands - it worked, but not like I wanted it to.
Ahh well, I think I'm done with this one. Here's it for you all to enjoy!
