    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.

I made a web page where you could generate these things with some parameters, but this JS also looks nice.

Did not find a way to get it to start over more quickly in 140...
u/13thptr

Multiplying by 0.2 is equivalent to dividing by 5 (gain 2 bytes each time) and cos(0.7rad) is roughly 0.76 which can be written .76
u/13thptr

also moving c.width^=0 to the first part of the for loop saves 2 bytes

Nice, thx!

you can also use .7 instead of 0.7, might come in handy next time

I ran out of characters. But this is cool... i guess

u/13thptr

you can remove the brackets of the for loop, doing for(i=999;i--;) is 1 byte shorter over your approach and 1920 can be approximated with 2e3
u/mildlybean

thanks, ill keep that in mind for future dweets
