Video of a sandbox equipped with a Kinect 3D camera and a projector to project a real-time colored topographic map with contour lines onto the sand surface. The sandbox lets virtual water flow over the surface using a GPU-based simulation of the Saint-Venant set of shallow water equations.
We (the UC Davis W.M. Keck Center for Active Visualization in the Earth Sciences, http://www.keckcaves.org) built this for an NSF-funded project on informal science education. These AR sandboxes will be set up as hands-on exhibits in science museums, such as the UC Davis Tahoe Environmental Research Center (TERC) or Lawrence Hall of Science.

The sandbox is based on the original idea shown in this video: http://www.youtube.com/watch?v=8p7YVqyudiE
The water flow simulation is based on the work of Kurganov and Petrova, "a second-order well-balanced positivity preserving central-upwind scheme for the Saint-Venant system."
The complaints about Apple's new bendable iPhone 6 Plus is making its rounds on social media, and here's a round up of all the jokes we've seen so far. Apparently, Apple is said to be replacing the bent iPhones if they pass the "visual inspection" and qualify for warranty replacement. Check out the jokes: Read more
Here's an interesting video to check out, which goes into discovering whether or not periods make women moody. There's just so many chemicals floating around that we misconstrue that PMS = period. Which is not. Check out the video for more: Read more
