Anyone ever tried lasering GOBO's for high powered projectors. GOBO's (GOes Between Optics) are glass slides that goes infront of the lens to create huge advertisements on buidling walls just like this. We are planning on buying the projectors. However, the gobo's cost $120+ to get it customized from most manufacturers. I heard it was a laser process, so maybe my laserpro or universal can get the job done ?

GOBO's use dichroic (heat resistant) glass slides and heat resistant coloring on it. So lasering away the logo or text could produce the needed effect. Has anyone ever done this or can shed light on the whole process ?
