Pulled a Game out of my Afro last night
Figuratively of course. I saw the latest topic for the http://experimentalgameplay.com monthly experiment for a game with no buttons. I've been up for the last 12+ hours making it, by far the quickest game I've ever completed. So I present: Banana Defense

The premise of the game is you control 4 canons that shoot oranges(?) at these blue dudes who are trying to eat your banana (randomly located). When you mouse over the canons, where your mouse is will move the canon in that direction and when you mouse over the 'fire' buttons in the corners, they fire. Really simple.
