    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.

Circle Wave Squared

I figured out the circle wave looks really good with an evenodd fill. Also, you can change the 4 in j=4e3 to change number of layers, and toggle between filled or not if even/odd

Circle Wave #beesandbombs 🐝 💣

u/KilledByAPixel

This one was fun because I found a way to combine the loops and hide the start/end gap that removes the need for a beginPath. Freeded up enough space for background color, or something cool in a remix.
u/aleamb

yeah!
u/pavel

Buggy in Safari. Jagged things sticking out, i think from the line end-caps, also breaks after a while because you didn't wrap-around the angle in arc.
u/pavel

Huh, actually both issues are resolved by modding the arc angle by 2*pi

how do these escape char ones work? is it decoding something? perhaps it is converting every unicode char into two ascii chars?

You can replace eval with throw to get the code. Compressed with d/14282
