    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.

Never heard of it :) time for a quote: "Absolute Ignorance is the artificer [...] in order to make a perfect and beautiful machine it is not necessary to know how to make it" - Robert Beverley MacKenzie, 1868 ... gona keep my monkey fingers typing, maybe I will learn something.

Move your mouse over the canvas. Also, try changing 64-1 to 64

Why you use 64-1 instead of 63? 😂
u/tomxor

because that would only be 139 chars silly :P

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
u/tomxor

moire: Z=(X,Y)=>t
u/katkip

Any formula has a moire actually
u/mildlybean

Especially (X+Y)%2==0?0:S(t*2)*50
