Gold panning takes patience. A gold panner looks for placer deposits, fills the bottom of his/her favorite pan with anticipation, and then meticulously manipulates the pan to filter gold from the heavies and black silt that layer the dark bottom ridges of the gold pan. It’s not easy work, but it can be rewarding, given the staggering price of today's gold.

Here's the first revelation, and it's quite interesting: Optoma offered a wonderful idea this summer. They showed how to use an ultra-short throw DLP 3D projector, along with interactivity, to create a unique interactive tabletop display surface. For a live demonstration, see this video.
It’s basically an interactive whiteboard, with 2D or 3D, on any tabletop surface. This makes a lot of sense for schools, learning centers, museums, and other spaces that like to conduct smaller, more personalized tabletop simulations or exercises. It even makes sense for school and emergency preparedness training for small group training. I expect this approach to really resonate with educators. Think about how you might apply this idea in your own setting.
