Lighting effects with clear plexi-glass podiums. We have an annual award show, which we call Honors & Awards. Well we have these three clear plexi-glass podiums. The year I designed the set I put the podiums on raised platforms with up-stage escape stairs. Underneath the podium base I cut out a hole so that light from a color scroller could shine through and refract through the plexi to shine whatever color I had in the scrollers. The two caveats are/were as follows: 1.) Use older platforms. 2.) Line the base of the podiums top surface with opaque white paper. That way the reader is not shot in the eye with bright light.
