A wooden base supports a large black cylindrical cast iron object. The cylinder has a spherical cap at one end and a collection of seven lenses at the other. It stands on three legs, one in the middle of the end nearest the cap, and two on the end nearest the lenses. On the underside of the cylinder is a light bulb with a standard power cord attached to it. The lenses are grouped vertically, two-three-two, and between the light and the lenses is a removable slide with a glass pane in it. The pane has seven triangular spots on it corresponding to the position of the lenses.
