For some Angry Birds fans, simply clicking on a pixelated screen to lob squeeling birds at fat green pigs is not enough. Simon Ford decided he wanted to create a real-life slingshot to get the job done, turning a virtual game into one that's (somewhat) physical.
First, he carved his own slingshot. Then he embedded two sensors; an accelerometer, which measure the inclination of the sling shot and a "rubber strain" sensor which measures how strongly the rubber band has been stretched. This information he then assigned to a corresponding mouse pointer movement. All that he needed to create the device was a USB connection point and mbed LPC11U24 NXP microcontrollers. And a slingshot, of course, which you can carve from a tree of your choice.
