A Croquet Winter Wonderland

It has emerged as a type of practice here in the United States for people to begin putting up holiday decorations on the weekend after our annual Thanksgiving celebration. In keeping with this, I offer this link to a new video from the folks at EduSim. In this one, they use a projected Croquet space in combination with a very compact eBeam input device that converts any surface (in this case a regular wall) into an interactive surface. The result is an on demand and relatively low cost interactive white board solution ($800-900 US) that, in combination with a data projector ($600-2,500 US) and Croquet software (free), may represent the beginnings of an economical alternative to traditional in-classroom visual communication boards (the typical front-of-the-classroom whiteboard/bulletin board installation is comparable in price). Could this be the earliest manifestation of a new form of broadly available classroom media for K-12?
