This colorful sandbox that changes color as users "play" with it may seem like a toy, but it's actually an ingenious way of creating topographic models. The Augmented Reality Sandbox projects real-time, colorful topographic map data onto sandy surfaces allowing participants to alter topography in real time.
This is one wild blanket. It's all embroidered up with sensors, conductive tassels and resistors that enable it to gather enough information to create a 3D model of itself no matter how it is folded or laid out.
