    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.

Can reduce this down to 118 w/ with(x)fillStyle=hsl(${t*40%360},100%,50%),beginPath(),arc(t*1e4%1920,0,100,0,7),fill(),drawImage(c,0,0,1920,1123.2)

Lol!
u/veubeke

Fun hack: using *6 instead of *5 for the index adds a 6th element containing NaN. The 6th line is visible but not the snail because drawing the snail involves the NaN value.
u/gabrielsroka

neat, but are the snails going backwards?
u/innovati

you're too silly :3
u/tapgiles

What's with the _?
u/veubeke

@gabrielsroka: if you have an emoji font with a snail looking left then they’re going backwards, yes
u/lionleaf

Going backwards on my phone, but forwards on my laptop. This should be part of the snail emoji spec!!
u/veubeke

I’ll bring it up at the next snail emoji consortium meeting.
u/gabrielsroka

lol, they're soooo slow, they're going backwards. and yes, mine look left
u/gabrielsroka

according to http://emojipedia.org/snail/ Apple is in the minority, and Windows 8.1 looks left
u/magna

On my computer, the best snail always wins.
