fractals are pretty simple once you wrap your head around them you make a global array then make a loop and put the global array in for loop make a box there rotation scale and length its length times scale time math.cos(rotation); to get end point store it in array in for loop next iteration start with array.lastChild position in then you make two branches the opposite direction and you would calculate those endpoint and iterate the endpoint in array to start-point scale and rotation can be iterated for var i = 0 i < array.length i++ ){ if( i < 10 ){ code }} you have to that or it goes on forever
