    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.

(golfed -10b) 🌍🌝 Moon floating around earth (both rotating now)

u/SockTaters

not sure if this fixed or introduced a bug by rendering all 8 phases of the moon. It seems to fall out of phase fster

u/SockTaters

Might have been done before, but I didn't see anything under the barcode hashtag. Between u, t, c, x, S/C/T, and R, R looks the best to me.
u/tomxor

Damn that's small. For some reason this elicits the sound of a dot matrix printer in my head.
u/KilledByAPixel

nice! there are a few other barcodes, this is my fav: https://www.dwitter.net/d/7868
u/fentbiggesthater

ive been waiting for an hour, what happens?
u/SockTaters

u/fentbiggesthater it draws a barcode starting in the top left corner. Should be visible after a few seconds
u/SockTaters

Also I meant to say that I didn't see *this method* for making a barcode before, not that I'm the first to make a barcode. I could've worded that better 😅

#FizzBuzz in 44

u/SockTaters

This is a little refactored, but u/DaSpider's solution also works in 44 characters with just the t|=0 trick. A slicing solution is also very close at 45 char: t|=0;throw'FizzBuzz'.slice(t%3&&4,t%5?4:8)||t

Voxel Rendering

u/SockTaters

The math in R() ensures the farthest voxels from the viewer are drawn first regardless of rotation. If a 2**X by 2**X grid is labeled the obvious way (with the numbers 0 to 2**(2*X)-1 left-to-right, top-to-bottom) and n is the index of a given corner, then i^n maps i to an ordering that starts at n's corner and ends at the opposite corner. Rectangles of 2**X by 2**Y might also work. The math in R() is somewhat obfuscated for golfing purposes.
u/SockTaters

n=[0,3,12,15][0];for(i=0;i<16;)console.log(i++^n)// try these 4 corner indices
