[Fluxus] circular water simulation particle system

[evan.raskob [lists]]

i've been obsessed with circles, lately - here's me playing around  
with circular particle systems and transferring energy btw particles  
(code included):

there are a few funny bits in the code - its experimental, of course!   
the logic is adapted for a circular particle system from dave's 2D  
water simulation example

comments always appreciated.  this will become a music video at some  
point...

cheers
