    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.

Remix with four points

u/taupelink

some pattern details are just an artifact of the "S(i)" (sine of i radians) in the golfed code

u/sigveseb

Nice, is the compression worth the bootstrap overhead?
u/iverjo

Crazy stuff. How does it work?
u/3bl3gamer

No, it does not. Decompressor doubles characters number, but takes 75 characters by itsef. So no profit, just making some unreadable code even more unreadable :-)
u/3bl3gamer

It works by converting N utf-16 characters to N*2 bytes and then converting this N*2 bytes to N*2 utf-8 characters. This N*2 characters is JS code.
u/iverjo

A for effort

It is a bug in the website. I'll see if I can fix it.
