    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)

nice, i think this is the smallest dragon curve on dwitter! #dragoncurve
u/HellMood

<code>for(y=i=5e5;i--;)x.fillText(0,y=y-t>>1,t-=1630*(t&1)-y)</code> to get an image fast, but then it's not very responsive.

nice! long time no see, welcome to dwitter

54: for(y=i=1e4;i--;)x.fillText(i,y=y-t>>1,t-=1e3*(t&1)-y)
u/HellMood

cutting my carefully crafted number for filling most of the screen does not directly count ;)
u/HellMood

Xen, Cool stuff on your side! How do you do the code markdown?
u/Xen

you know my style lol... pair of ` for code

You've reached the end.
