    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.

Are you from 3018?
u/aleamb

superb!
u/Batrachus

Right now the formula is generating surface points on a coil-like curve. You can get a more ghostly banana by modifying the last two arguments of xfillRect to 5 and the first argument of Math.max to 0.03. You can probably golf this further by drawing circles with radius of M on a simple curve going through the banana's core.

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
