Students at the Copenhagen Institute of Interaction Design have developed the Super Angry Birds Controller
Super Angry Birds is a force feedback USB controller for Angry Birds that simulates the feeling of a slingshot,” they say. All the controls found in the game are available in this device. You can control the pull, the angle, and of course trigger the special power of the bird. We hacked a motorized fader found in audio mixing consoles to simulate the force you would feel when using a slingshot.
