    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
u/magna

On my computer, the best snail always wins.

Great idea! :-D

This is great, and what a luxurious use of 100's instead of 99's :P

great colors. if you make i/t/S(t/10) it is pretty funky
u/donbright

make a = i/t/S(t/10) i mean

that's a cool edit! totally different but somehow similar
