I can’t recommend projectors with such a low throw ratio. The main issue is that even moderate topography in the sandbox will have surfaces that are at glancing angles to the projector, causing poor alignment and low brightness, or are even facing away from the projector, causing self-shadowing.

A 1.0 throw ratio is practical because it puts the projector at the same height as the Kinect camera, but ideally, the throw ratio should be as long as possible for best projection quality.
