    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.

Stack of Hearts

u/vain

Nice!
u/vain

Btw... shouldn't "[i%5]" be "[i%6]"? Else you could save 1 char. :) What do these three points mean you used here: "fillText([... ,'" ?
u/BriSeven

Whoops, you're right. The ... is the spread operator, it splits the string in a unicode friendly way, and assigns the individual characters to the enclosing array literal.
u/BriSeven

@vain do notifications work on dwitter?
u/BriSeven

the ... next to the string is actually a special case. more generally it works on anything that implements the "iterator protocol" which is lots of stuff, but mostly arrays and array like things.

Accidentally created an optical illusion. Watch it for a while, then pause it (scrolling a bit can do this on dwitter), and it will appear to continue to move.

u/BriSeven

another part of this that interests me is that it appears to have a kind of lighting effect that changes as it rotates, but as I built the cubes up in layers of alternating colors, the lighting effect comes accidentally from the way the layers move further and closer apart as the rotate.
u/pavel

this is a nice trick
