I designed this show awhile back. I had four fresnels and a tonne of those horrible yellow work lights. I used the fresnels as a general wash
. We mucked up the work lights and persuaded the director to get the actors to move the work lights around on the floor to various spike
marks. We took the grill off and added two mounts for a par
64 size gel
frame. The actors moved the lights and changed the gel
during the various scene changes. All things considered it acutally looked quite interesting...
Not sure if that helps...
