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.

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

lol and now I wonder why I didnt just do this from beginning.. for(i=768;i--;x.fillStyle=hsla(${i+99*S(f)},99%,50%,.5)i<216?x.fillRect(0,5*i,2e3,5,f=t):x.fillRect(5*i-1080,0,5,1080,f=t*2)
