i'm messing around with AE shortcuts to creating molecular level geometry - this is 3D - one cool thing that i am playing around right now is with the individual particles having transparencies and images inside of those transparencies (if that makes sense...) ---> that way when these all overlap it'd super organic looking. you can rotate this guy in z space and/or use it as a custom particles within another particle system. render time on these frames was about 20 seconds each, and they react to 3D lights
