Hi Paolo, I wrote an IFS parser too, hoping to figure out how K-IFS 
fractals work. It didn't really help, but it was a fun diversion <g> 
It's intolerably slow and not very efficient... The attached image took 
31 seconds to parse, and has 193317 objects from 28 iterations. The 
reference I modeled it from used fewer samples, yet possessed higher detail.

Kaleidoscopic iterated function systems, when computed with an escape 
time algorithm, are much more efficient. They take less than a second to 
parse and have a minimal memory footprint... and the result is just one 
object :)

Now if I could just get the Menger Sponge working... I'm about to 
concede defeat :(
