    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.

sierpinski triangle :D
u/xem

It'd be nice to have a blog post explaining it :) (please?)
u/trupples

I didn't look much into it but it might have to do with a thing I read about once where if you have a point that "walks" half the distance towards a random corner of a triangle you'll end up drawing a sierpinski triangle sorta like you can see in https://www.dwitter.net/d/5097
u/trupples

And according to http://distrustsimplicity.net/articles/sierp… if you were to use 4 points instead of 3 you'd get a tetrahedron like in this dweet. Fascinating stuff

That's a really clever illusion, love it
u/magna

Heh, thanks! Brought it down to 123 chars in hopes of adding occasional mistakes like skipped characters / typos etc., but couldn't immediately find a way. In case anyone wants to give it a shot: https://www.dwitter.net/d/2522
u/donbright

:o
u/Polyducks

Could you make a random function to skip odd spaces?
u/magna

It has to be a deterministic PRNG so that the places that are skipped are persistent. Otherwise, it would just look like a random flipping of characters. I thought about it, but couldn't immediately find a short solution.
u/Polyducks

That's a great point. Dwitter is such a mind twister!

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
