i went to see John Klima's show in LA called toy world and really enjoyed it. (here's me on the kiddy ride horse navigating the terrain of Afghanistan) the show addresses issues in gaming and uses real data from the Department of Defense in some of the pieces. this one shown above has an interesting interface using light-sensitive switches. so when you wave your hand over the green matrix (a mapped representation of the moving image on a matrix) of these switches to cover the light that is shining down from a projector above, you will change the topology of the projected image of a woman's body via mechanical triggers beneath the surface.
