    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.

It will graph any equation you put on the first line. Give it a try, I'd love to see your remixes!

S((X*X+Y*Y)**.5/4-t*16)*16 is interesting
u/tomxor

Neat! #application , shameless plug to my old retro version: d/12669
u/tomxor

yours has a much nicer resolution: Z=(X,Y)=>S((X*X^Y*Y)**.1-t*8)*16
u/katkip

Z=(X,Y)=>S(X/9*C(t)+Y/9*S(t))*9 is cute

moire: Z=(X,Y)=>t

You can change the position of the "light" by changing the two numbers in Math.hypot(). Also, golfing tips welcome!
