You can project all of these effects with one basic unit with a throw of 10 to 200 feet. The Scene Machine will hang in any position and can be installed permanently or moved anywhere you need it. All parts and Effects Machines are changed or installed without tools. The Scene Machines are modular projection systems, designed for professional use, but simple enough for use at a high school stage. With interchangeable parts, you can project moving and still effects from one unit. Built around the projector head, the various Effects Machines slide onto the head and lock securely without the use of tools. Lenses slide and lock onto the Effects Machines in the same manner. All accessories are lock-mounted onto the machines by hand, and once seated require no tightening or clamps. GAM has a video available which demonstrates the Scene Machine and many of the available effects. Many of the available accessories are shown on the right, a complete list is available from GAM.
