    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.

Slightly more space-filling line pattern

u/Agnes

Huh, this was drawing patterns for me yesterday but today, on the same computer, it's not doing anything. Weird???
u/Xen

works here, maybe you should try putting the Q= inside Path2D so its declared on fist pass

The graph r=theta spinning around the origin. 65 characters to play with, so there's lots of remixing potential. Try messing around with the trig functions, it leads to some fun results

Go fullscreen, stare at the center for 30 seconds, then look away from your screen (e.g. look at your keyboard). #opticalillusion

#default with transformation matrix setup. Z is zoom factor, A is rotation angle. Go nuts.
