    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.

Welp, immediately figured out the issue! I need to enclose the for-loop with curly brackets #JSnoob

Not a spiral but still wavy! I couldn't figure out how to add color for some strange reason... any suggestions?

Symmetries among singularities

nice granularity

Thanks u/andrea270872! I find it reminiscent of DaVinci’s sketches.

My first dweet: a glitchy spiral! Very excited to move from lurker to contributor amongst all of you incredible coders and artists here on Dwitter!

Welcome to the dwitter family!

Nice style!

Here's some quick golfing down to 68: p=7*t**3;A=3e3/p**.2;x.fillRect(960+S(t)*A,540+C(t)*A,9*S(p),9*C(p))
u/Xen

A=3e3/(t**3)**.2;x.fillRect(990+S(t)*A,520+C(t)*A,9*S(A),9*C(A))

Thanks, u/Xen and u/magna! Of the two suggestions, I'll have to side with u/Magna's for golfing it down while maintaining the glitchy-ness!
