The I Am More Than My Thumb thesis project by Kellee Santiago (founder of thatgamecompany) is an interface experiment using arms spread to fly while playing the game Cloud. Pixelsumo writes: "This project allows you to control the character using your body. Tilt your arms to turn and raise them to go faster or lower to slow down. It uses the PhaseSpace motion capture set-up, essentially cameras tracking LEDs on the wearers body."
Follow the link for a couple more games that aim to control in-game flight with your arms, if only to embrace that boy trapped in a man's body.
