    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.

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!

Slightly more space-filling line pattern

u/Agnes

Huh, this was drawing patterns for me yesterday but today, on the same computer, it's not doing anything. Weird???
u/Xen

works here, maybe you should try putting the Q= inside Path2D so its declared on fist pass
