    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)

My eyes can't decide what is foreground and what is background. I think it all depends on the edges: when the black is further up the edge, white is foreground.

u/magna Thank you. I use this actually as a sort of mindfulness training. Observing a tiny, tiny rectangle being born in the deep middle, trying to follow it, slowly moving and growing, until it reaches you, at its maximum size, fading totally right in front.
