Pretty Fly for a Web App is a browser-based 3D flight simulator that allows the user to fly a plane through a three-dimensional space using their body. If you\'ve ever seen a child running around with their arms outstretched, pretending to be a plane, then you\'ll be familiar with the control scheme: your arms control the roll, your head controls the pitch and your hands control the yaw. Pretty Fly for a Web App was built using Processing, Node.js, WebGL, three.js, the Microsoft Kinect and Greg Borenstein\'s Skelestreamer framework and runs in all modern browsers.
