    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.

Nice work!, I actually did try a solution with fillRect - but it totally kills my laptop, runs kinda ok on my phone though (I get around 11fps with this dweet on my laptop, 28 on my phone)
u/danny@hille.dk

btw nice trick with ++e, i haven't seen that before, I'll put it on my toolbelt right away :-)
u/KilledByAPixel

Yep, had to make some sacrifices for speed. You can do w=127 and get a pretty good fps!
u/danny@hille.dk

this is my aptempt: reduced the resolution to get at bit more performance: c.width=w=127;for(m=w*w;m--;x.fillRect(m%w,m/w,1,(Y*(o=(3-(4-5*e+S(t))**.5)/(e+1))*w+t*w&w^X*o*w&w)/w))e=(X=1-4*m/w/w)*X+(Y=-2+4*(m%w)/w)*Y
u/danny@hille.dk

with the ++e trick its only 137 bytes :-)
u/danny@hille.dk

Sorry i hadnt seen you wrote back, yep i did 127, (any pow(2)-1 will work for the xor pattern)
