    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)

u/BuRRak

Nice! Looks quite similar to my dweet, d/7996 :D
u/iverjo

You just taught me that c.width=-1; actually sets the canvas width to 300. Clever!
u/BuRRak

300 is the default size of a canvas so giving a negative number will just reset it to defaults i guess
u/prplz

iverjo: I give credit to u/jylikangas for the -1 width trick
u/prplz

BuRRak: Thanks, same goal different approach :)

thanks. iverjo that is super cool! i wish i could figure out how to combine that with this.

Did it, but at 150 chars, will share remix if I can get it down to limit.

Eh, not the same subtlety, but this is what I've got https://www.dwitter.net/d/1479

New version where larger snowflaskes fall faster than smaller ones, but had to remove the random wind. https://www.dwitter.net/d/1520

quest for the most lines in a 6 byte dweet? anyone want to try further

Show more comments…
u/erin

ok, i have a scoring system
u/erin

divide the amount of bytes by the lines
u/erin

so my score is 1.5 (smaller = better)
u/DaSpider

throw loop
u/erin

ohh sick, nice one
u/Xen

throw u+=u
u/DaSpider

We have a winner
u/erin

u/xen, technically breaks the "rules" i set, it has to throw everything at once
u/Xen

oh :-( ok...
u/Xen

throw [...Array(5e3).join(loop)]
