The University of Hartford is putting of The Mystery of Edwin Drood and is looking for a custom show title gobo to be borrowed. This is one of our non budgeted productions.
If you have several lights to dedicate to the job (or a CNC router), you could try to cut it out of tin foil or the bottom of a pie tin (or a thin piece of steel). Or you could cut it out of non-flammable fabric and hang that in front of the light. Other than that, you could try using a projector.
