    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.

u/kchplr

Noticed it is very slow in firefox, has lot of artefact on Safari and doesn't even render properly in stable Chrome. The only browser rendering it correctly is Chrome Canary. Oh, well.
u/kchplr

Here is a version which renders correctly on stable Chrome : for(x.fillStyle='rgba(0,0,0,.1)',x.fillRect(0,i=0,2e3,2e3);i<7;Y=S(i*2+t),X=(C(2*i)+C(t+i+Y)),x.clearRect(960+X*450,536+Y*500,20,9))i+=.002

Best seen in fullscreen while listening to JOY DIVISION by UNKNOWN PLEASURES

for the code golfers around, I got this one down ~112bytes without the colors and less interesting noise
u/raurir

Well, I guess it's the thought that counts
u/p01

Thanks for bringing up JOY DIVISION on Slack - https://www.dwitter.net/d/2108 is super well done as well.
u/magna

Is there a Slack for Dwitter?
u/FireFly

There is a general JS golf slack with a lot of dweeters in it at jsgolf.club

really nice, my favorite of this series. i notice the 'circles and squares' fractal / pseudofractal shows up a lot in this one, Moire style patterns. the symmetry is really cool too
