    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.

Hey, and if you tweak it a bit, you can use it on Valentine's Day -> for(i=5e4;i--;x.fillRect(99*X,77*-Y,k=f&t<2,k))X=i*i/t%20,Y=3*T(i+t),f=(C(X)+S(Y+C(X)*C(X))),x.fillStyle=R(-f*99)

u/Joachim

u/pavel I don't know why but changing this (i>>6)*36-D,35-D,35+D makes a biased maze
u/pavel

I think thats the trick to the original dweet. It's a golfed maze with a visual filter.
