just came across the pixish website, and it seems very similar to 99designs, but with more of a focus on photography and illustration.

Here’s how it works:

1. Create an Assignment. Ask for what you want.
2. Get Submissions. People create and submit their work.
3. Peer Review. Community voting helps find the best.
4. Pick Winners. Select your favorites and download.
5. Rewards! Winners get rewards.

i like what the internets can do.
