Augmented Reality with Flash
Here’s another “wow” project - FLARToolKit (FLash Augmented Reality ToolKit)
Your webcam, little bit of Papervision, the FLARToolKit, and you’re off.
It’s similar technology to that which powers “Eye of Judgement”, and is pretty cool. If you’ve got a webcam go and scribble a large black box onto a bit of paper and test it out.
