I don't remember whether this has been shared here before, but it's pretty neat.

Recycling my Facebook comment, and adding to it:

It looks pretty simple to build, but unless one can get a cheap computer that can handle the computational demands, it might be expensive. The components listed are a projector, a kinect camera of particular vintage(s), and a computer with a good graphics card. The processor and graphics card listed are about $750. I don't know enough if someone's old computer would be good enough to work.

What makes it simple is that the software has been released under the GNU General Public License. It would be nice if features could be added specific to teaching orienteering or other concepts. For example, gradients rather than contours. Or adding some way to tilt the sandbox under the fixed Kinect camera (originally for XBox) to show how the contours shift.

I was wondering if I could do this with an old computer by lowering the frame rate or something. They mention being able to turn off the water features, but they don't recommend it.

It's pretty expensive and it weighs a lot using their instructions:
Processor: $350
Graphics Card: $300
Kinect Camera: $30-40 off ebay
Projector: ???
200 pounds (~90kg) of white play sand: Up to $200.

It would be really cool to make a smaller one in a briefcase or something a bit larger. You could possibly get away with one of those pocket-sized nano projectors. If I were building it, I might have a heavy case with the sand and mounts for the other items, but then I'd keep the camera and projector and computer in a separate "clean case" to avoid getting sand all over them.
