This could also be worked as a killer promo. A Renderosity driven promo backed by prizing from hardware and software companies. Think big here! This negates an entry fee and keeps the government from seeing this as gambling. This benefits the entire community with increased traffic etc. Either way you do it it is a great idea to get people focused on creating again. A few media mentions could help drive this too...like Tech TV's "The Screen Savers". You want traffic... build it and they will come! I love brainstorming! Endorphins for everyone!
