headtrackr is a javascript library for real-time face tracking and head tracking, tracking the position of a users head in relation to the computer screen, via a web camera and the webRTC/getUserMedia standard. For a demonstration see this video or try out some of the examples with a laptop that has a camera and a browser that has camera webRTC/getUserMedia support (for instance Opera 12). For an overview of browsers supporting the getUserMedia standard see http://caniuse.com/stream.

The Web Audio API introduces a variety of new audio features to the web platform. It can be used with the canvas 2D and WebGL 3D graphics APIs for creating a new generation of games and interactive applications. The API is capable of dynamically positioning/spatializing and mixing multiple sound sources in three-dimensional space. It has a powerful modular routing system, supporting effects, a convolution engine for room simulation, multiple sends, submixes, etc. Scheduled sound playback is provided for musical applications requiring a high degree of rhythmic precision. Realtime analysis / visualizer support and direct JavaScript processing is also supported.

A tribute to the awesome wonder-wall by tha.ltd. And a demo of WebKitCSSMatrix. The wonder-wall effect is inspired by this great example, the Javascript Matrix library used is this, and the book covers are taken from here. The interesting stuff is the possibility of manipulate the transformation matrix of any element of the DOM, In this case we get the matrix given only the 4 end points of the element, which is done porting OpenCV's cvGetPerspectiveTransform function and some trickery, the JavaScript code is here. Right now the effect only works in Safari 5 (best) and Chrome 7 Dev. Roll over the elements and click them.

Moving Sonic the Hedgehog to the right caused the foreground to move past the camera to the left faster than the background, creating a faux-3D view of Green Hill Zone. We can create a similar effect on a web page by fixing semi-transparent background images to different sides of the browser viewport, and at different horizontal percentage positions.
