    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

This one also stopped drawing patterns for me after I restarted my PC. :(

Alien robot factory V2

Massive props to JWinslow in the Discord for doing almost all of the golfing! The last 15 or so characters were removable because 1.57 is an OK approximation of Pi/2 and because the dimensions were scalable by four in the transform.

This may be possible in 140 but I couldn't put the time in today. If you figure out how, post it as a remix!!!
