Infrastructures is a tiny doodling algorithm I discovered and first posted on Dwitter in June of this year.

for(j=1e4;--j;x.fillRect(a.x+=C(a.a+=((a.x+d%777)^a.y+d)/1e3),a.y+=S(a.a),1,.1))a=T[i=j%99]=t?T[i]:(d=Date.now(),{x:i*20,y:j**9%1e3,a:j})

This algorithm is very complex and interesting so I developed it into this larger work and released it on fxhash.
