There's nothing really special; a PSU to drive the lamp (possibly with some sort of dimming control), a changeable slide currently with a cylinder on, and a set of mirrors/filters(?) to provide two beams of light.
By the looks of things there's nothing to move the cylinder image around, nor is there anything to act as an LCD screen or anything so video could be projected.
My previous guess still stands, although i am completely at a loss as to why you'd want such a thing...
