Got a Kinect, a projector and a knack for code? If so, you can create a Star Trek-like holodeck in your living room. Microsoft has released the RoomAlive Toolkit, a software framework that lets you string together Kinect motion trackers to create interactive projection maps. You can use it to build anything from extra-immersive games through to art displays. This isn't exactly a trivial undertaking (Microsoft is promising lots of tutorials), but it means that you won't have to wait for someone else to bring your augmented reality dreams to life.
