A gobo, (a.k.a. decal, pattern, cookie), is used to create patterns or shapes with light. Most are made of metal - often old soft-drink cans or pie-plate can be used - the shape or pattern desired is cut out and the gobo is placed in the focal plane of the lantern. Others are made of etched glass. The desired pattern is then projected by the lantern onto whatever surface it is pointed at.
