The term Gobo is short for “Go Between Optics”, describing the location where it must be positioned in the light path of a gobo light. Whilst Gobo’s are not a new technology they are still being utilized on events the world over. In today’s event market they may have taken on a far more creative role as technology advances allow for more in depth and impressive shapes to be created.
