Imagine exploring Tudor London:  a man being pelted with rotten vegetables in the stocks; marvelling at a potato from the New World; children playing on the cobbled streets; soldiers bristling with swords glinting in the pale winter sunlight. For now you can, thanks to new (or perhaps fairly new) technology. Don a fetching pair of tinted glasses, and you're off. You use a special mouse which enables you to manipulate the picture.  As you move forward, the world moves forward and around you as if you were moving in three-dimensions.  A volcano, the trenches in world War one, the human heart, even the boudoir of the Earl of Rochester-there are countless applications for this technology and doubtless ones we haven't thought of yet. http://www.xpandcinema.com
