Actionscript effect?

look at experiment #3 here: http://www.heavy-rotation.co.uk/old/

does anyone know how this is effect is done w/ actionscripting?

i know you basically have to duplicate ur movie clip in some way, move/rotate in some way, and fiddle around with the alpha…except i’m not exactly sure how actionscripting works exactly in flash…still new to it…though i know java ;p

thnx
