Nice addictive online flash game (Innovative!)

Basically just looking for a flash game that is fun, good-looking and addictive. I would like to work with someone who has a very good grasp of English so that I can work alongside them and help with the project. A physics based game is preferred but not essential. PM me with your ideas for the game or even a quick demo, I will choose the winner based on who has the best ideas and who I think can complete the game best.
