/prog/ - Barnsley's Fern

Minimal Barnsley's Fern (lolwikipedia) in html and javascript:



<html><script>n=u=v=0

function i(){t=document.body.lastChild.getContext('2d')

t.fillStyle='green'

r=Math.random()*99

x=u,y=v

u=x*.85+y/25,v=y*.85-x/25+1.6

if(r<14)u=y/3-x/7,v=x/4+y/4+.4

if(r<7)u=x/5-y/4,v+=1.3

if(r<1)u=0,v=y/6

t.fillRect(50*u+140,525-50*v,1,1)

if(n<2e5)if(n++%99)i()

else setTimeout(i,1)}onload=i</script><canvas height=550></html>

Works on modern browsers (well, ok, works on Firefox and probably Chrome). It's also 348 bytes. Can anyone do better?

Oddly enough, sans no functional programming functional programmers seem to foot this bill better than python programmers.
Hey guys, why would anyone use a conditional when they can simulate the effect by continuation passing curried $ applied arguments to a catamorphic functor who evaluates the given idempotent unary function parameter and folds it based on an independent data type with accompanying functor to ensure catamorphic conformance.
