That's certainly one way to format it. The other way is to not have any deadline and just have a signup list of variations and check off variations as someone completes them. Maybe claiming a variation gives you exclusivity for a three month period?

I dunno, I'm just always in favor of figuring out lower pressure ways to do things as well as higher pressure ways. With the Big Bang-style approach, if we don't get 32 vidders right away, it loses the urgency instantly. With a more relaxed approach we can start small and gain vidders one at a time as they see a neat project and have time to make a vid for it.
