draw primitive with actionscript

[macbef]

ok one more question... i've turned it into the loader i wanted, and i'm really pleased with the effect, but the only thing is that it slows down when the flash movie is further loaded.. now i think that's because i've placed the "for" loop in an "onEnterFrame", because i thought that was the only way the loader can be updated.. but is there an other way?!
