Similar to Flickr, Pixish is a new online community to which you can post your own, and view other designer's work. 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 prizes and rewards.
