    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.

Golfed and slightly cleaned at https://www.dwitter.net/d/5543. Have fun with the extra characters!
u/Bugsy

(cleaned is referring to some slight blockiness on the right side of the animation, not the code. My code is much uglier :P)
u/BackendForth

Neat! TIL Javascript accepts python notation for exponents.

Golfed even further at https://www.dwitter.net/d/5601. Now there's 30 extra chars to play around with :-)

Simple terrain generation using midpoint displacement

u/iverjo

Nice alternative to perlin noise!
u/sigveseb

Very nice! And with the horizontal flat line we can pretend that is the sea level; everything above is a mountain and everything below is the sea :)

Sweet! Of course, I saw your work *after* I posted. I was going to try and unpack your technique today, so I'm pretty happy that you did this remix
