    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.

spot the pattern

u/iverjo

S(i*t*2246795327919) is kinda nice and smooth, with less patterns
u/iverjo

S(i*(t+9)*2246795327919) is even smoother (in the beginning)
u/donbright

these ones where you erase and re-draw are really interesting.

Nice field of grass (?)! Now we've got grass and water: https://www.dwitter.net/d/254 and water with a sun: https://www.dwitter.net/d/63
u/AndrewBetts

I was going for a misty forest look, but it's quite abstract so grass works too :)

At first I didn't realise it was multicolor. It gets interesting after 20 seconds, when the green color crawls from the bottom, and other colors follow
