cool. but whats the gnomon website...or alt.

I realised that because of the nature of the overhead shot, I can render bg, main logo, shadow matte, and then comp in some particle explosions between the logo and the bg layer. Do you guys have any ideas on how to create the spark effect? ie: I know particles are the order of the day, but how do I get that 'particle dies, then spawns lots of others' effect!!?! also, could you put up the gnomon website url? cheers.
