    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.

The lack of x.fillStyle is amazing.
u/pavel

Save 3 chars by incrementing Z by .1 instead of doing the math every time: A=S(t);B=C(t);for(c.width=X=128;X--;x.fillRect(X,36-125/Z,Z**.5/7,250/Z))for(Z=0,R=T(X/81-.8);(A*t+24+(R*B-A)*Z^64+(R*A+B)*Z)%15>1;)Z+=.1
u/tomxor

Ah yes! thanks pavel :) I did try to get rid of Z/8 once but didn't go far enough with the constants as you did.
u/tomxor

Can also now play with the marching granularity more easily to get smoother results... although it's very slow without an SDF for the fractal for larger initial steps.

love it!
