    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

NB This dweet looks different on different browsers. On iOS Safari it does not look the way I intended it.

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

u/NiekD

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
