    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.

Pseudo falling physics

u/iverjo

Deserves more kudos :D
u/BirdsTweetCodersDweet

changing the last part to ... **2*25makes it more realistic, with more gravity and even a little bounce at the end... Also, removing the W variable saves you a byte :P
u/jylikangas

Actually you could use T in place of W and use it in place of every 20 to save 3 bytes. :)

u/fujimotos

Changing the callback to "x.fillStyle=hsl(${d++*25},50%,50%)" turns it into an abstract art generator :)

swapping PI/2 for PI/5*6 gets you pentagrams :)
