Scanner paints a virtual crime scene (New Scientist). Basically, a New Zealand-based company is working on technology that lets you use a digital camera and a heap of lasers to build a 3D model of a real-world environment. The article is about how they're going to use it for forensics, but my first thought was how cool it'd be to make maps and models using a method like this. Yeah, it's a bit gimmicky, but it'd also be a hell of a lot of fun. "No, I bought these legos for work. Serious work."
