Yes, another contest (we aren't affiliated, just like to spread the word). This one is from Pokki. You have until November 15th to submit your HTML5 app and have it approved for posting on their app store. Pokki is a desktop app platform that combines an interface, a development framework and an app store together into one package.

Teams of up to three developers can band together. Apps will be scored on utility, appearance, user experience, and quality. There are three prize purses: first place wins $30,000, second wins $13,000 and third wins $7,000.

You can read the details, the judging panel, sample Pokki apps and other information here. Good luck!
