    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!

Cover of "Computers And Automation And People" magazine, January, 1973. I was able to recreate the image based on a small description (in page 5): "Front Cover Picture: The front cover drawing, called "Phropase", was produced by an Algol 60 program, drawing straight lines ax + by + c = 0, where a, b and c were "stepped arithmetically in nested loops". The computer used was an ICL 1904A, driving a Calcomp 1934/6 plotter. The programmer artist is Nihan Lloyd-Thurston.
