This sounds so awesome. I would definitely (barring unforeseen events) participate if it included vids(with a short minimum length). Otherwise I wouldn't be able to. Also, not something I would do myself, but it would be great to open it up to other arts like crafty stuff, although delivering them to the recipient would be tricky to arrange with anonymity--probably would need mods or volunteers to give their addresses and be go-betweens? Anyway, basically, the idea of including offline art is worth a thought, IMO. It might not be workable but I'm very excited lately about expanding the idea of fanwork beyond "fic and pictures(some of them moving)." :)

IN SHORT: A+++ idea \o/
