    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.

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

On my computer, the best snail always wins.

reduced it by about 15 bytes in case you want to try to do something else with the extra room: c.width|=0;for(i=16;i--;)x.ellipse(1e3+300*S(t+i/9),500+50*C(t+i/9),160*S(-i/2)+160,50*S(i/9)+5,1.6+S(t)/2,9,0,7);x.stroke()
