Sketch3D

Sort of like Etch-a-Sketch 2.0, Sketch 3D lets you draw with dials, but includes an extra knob to represent the third dimension. It also includes 3D glasses so you can appreciate your work. Connect Sketch 3D to any output such as a LCD or plasma screens to draw and show off your artwork. Sketch3D uses cameras to simulate human eyes and creates the illusion of 3D images making your drawings seem to literally pop off the screen. Source
