Pfunked might support artists starting their own funding campaigns for creating art for FLARE, as he did with Justin's. Here are some asset ideas.
Then there's the option to offer high-quality art for being 'funded into free' at OpenGameArt. The current target is $130 for this dwarf warrior.
I wish there were (more) open source projects at 8bitfunding, Kickstarter, Fundry and IndieGoGo. The only open source game dev projects I found are a flash game (successful), FAR Colony and an interactive fiction engine iphone port (successful). I'm sure not only full game projects could make use of these fundraising services but free content creators as well.
Slick contest - art by danc
Then there's a game competition by the Slick java game engine. Check the image above for rules and prizes.
That's about all I can find and think of right now. Got anything to add? :)
PS: do you use flattr? Then share your data for great justice! If you're not using it yet but are sharing content on the web, then start using it already! :D
PPS: Wesnoth is still offering $200 for a swamp sound loop.
