    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 #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
