A group of students is gathered around a square table, on each side of which sit four small maps. In the center is a much larger map. The students are engaged in an animated discussion of key topographical features they are observing and the geological processes that may have produced them. Much pointing and tapping on the table punctuates the conversation. Then, to illustrate a point, one student grips and tilts the table, and a small picture from the edge slides to the center. The student applies a little clockwise torque and zooms in on the picture for a much more detailed view of the terrain. This magical piece of equipment is the Tilty Twisty Table. The brainchild of developers at Onomy Labs (www.onomy.com) in Menlo Park, California, the Tilty Twisty Table is a sturdy pedestal table augmented by a computer and a projector that casts images on it from overhead. By tilting the table, users move the images from the edge to the center; twisting it allows users to zoom in or out on the center image, making it possible to look at a very large document or picture in a small space. Because the table encourages collaborative examination, its potential for classroom use is great. Beyond the obvious geography lesson, a Tilty Twisty Table could be an invaluable tool in other subjects.
