F*cking cool rubber/morphing cube. Never saw this kind of fx before. Fantastic!

where do you get the inspiration for cool effects from
u/cantelope

dweets are sometimes harder to be ultra specific with a goal, due to the obvious constraints, but a big piece of my whole graphics repertoire is 3D math, sooo myself? haha not sure
u/tomxor

So true. More often it's just the gradual emergence of "what if"... then after a while it may or may not fit, or by the time you've played with it long enough something else tangentially related emerges. It's all part of the fun.

Sometimes what you end up with is nothing like what you planned
