    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.

Using setLineDash as otherwise its too slow to draw all the squares

u/Xor

Neat!

FYI: This dweet looks different to me, depending on whether I'm viewing it on iOS/Safari or on Chromebook/Chrome. On iOS, there's more detail even in the dark areas. I'm guessing it reflects a difference in how the 'hue' is implemented, but I dunno.
u/sigveseb

Awesome! Love dweets that expose browser implementation differences like this. Looks cool too :)

Fake Perfect Maze

u/aemkei

Build using the "Sidewinder" algorithm. A "perfect" maze has no loops and no isolation. I cheated a bit and the edges are not 100% right. But it fits into 140 chars!
