    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.

Down to 117, looks nicer on the canvas too... Still no room for typos though!

#quine that "types" itself on the screen

u/ETHproductions

The eval("...") is necessary because... well... just try with (f=_=>{...})() instead.
u/ETHproductions

I guess u/magna did a much better version already, go check his out: d/2516
u/BalintCsala

We should probably instrument anything passed to eval too...

Figured out how to draw a rotating sphere from a black and white pattern. This is the pattern being used here: https://i.imgur.com/khgNg7E.png
