Abstract
A kit for creating perspective drawings, teaching the creation of perspective drawings and method for making the same. The kit provides a pair of perpendicular supports, with the upright support having a transparent portion formed therethrough. A number of geometric objects are placed onto the flat support and are illuminated by a light source. The perspectives of the objects cast are captured by an appropriately-positioned screen. A sighting device is provided to focus the perspectives of the objects cast. A means for recording a copy of the perspective viewed onto the transparent window is further provided.
