    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.

Hex Spin

u/rep_movsd

Very clever - each hexagon moves in a circle and spins, but alignment makes it seem like a roll :)

This is nuts. Or bolts. Hex nuts/bots.

u/Jasper

Heya, I'm new to the site - what's the purpose of the OR in T=t|0? Is t sometimes undefined?
u/rep_movsd

t is time, but its in floating point, t|0 makes it an integer

This is a bit more accurate version, but it's hard to do this low res, try it yourself.

Shave 3 chars: (i>>5)*C -> i&-31
u/KilledByAPixel

you can also do i>>5*C, but both ways distort the image
u/aleamb

I don't rightly know why, but i&-32 seems to work without distortion as far as I can tell

To centralise #text vertically, add ~fontSize/3

u/joeytwiddle

To centralise horizontally, subtract x.measureText(T).width/2

(I think u/f8f82804 showed me that trick)
