Gobos are pieces of metal with shapes punched out of them; when they are placed in front of a light, the shape is projected onto a wall or the floor. Get one made with a company logo (or more than one: duplicates are less expensive), and it can be reused at all sorts of trade shows and events, saving money each time on props and more complicated lighting setups. Bay Stage Lighting in Tampa, Fla. (813-777-1069; baystagelighting.com), charges $125 for metal gobos. Note: The company also makes glass gobos for $238 (glass is more durable, as metal gobos eventually can lose their shape). Thanks to Kelley Rexroad, principal consultant of Krex Consulting, based in Odessa, Fla., for the idea.
