    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.

Takes a second to get going due to the limitations on how I could kick it off. The 184b version looks much better; I may post it when I'm satisfied with it.

Fun! #bounce
u/cantelope

the last paramater of x.arc can be 7, 8, or 9 as a single digit that closes the circle.. i usually go with 7 because it's the closest integer > 2π, but it's interesting that you go with 9 usually :)

Diet Sinewave Pattern, now with only 108 characters! (Had some leftovers from my original dweet idea that were clogging up the charcount, plus optimized the loops and positioning)

u/BalintCsala

98 chars: for(c.width|=y=40;y--;x.fill(),x.beginPath())for(w=33;w--;x.lineTo(60*w,S(t+y/5+w/2)*50+30*y-75));
u/firegodjr

Thanks! I'm a bit new to reverse loop iteration, so I didn't think of replacing the --w+1. How does the c.width|=y reset the width properly, though?
u/BalintCsala

It sets it to 1960
u/iverjo

Cool! Deserves more attention

Ah, u/BalintCsala beat me to it... :)

96 chars if you replace --w+1 with w--
