If you are having the customers acclimate to TV screens, I would have the plexiglass and behind the actors head another TV playing white noise or clips of saw scenery to give the same intense light as a video presentation. It also protects the actor from the occasional return visitors that would like to reach into the screen or whop the guy on the nose.
I would have the stack of TV faces slide to the side and walk/dart out rather than dive out.
Another fabulous post from the U.S.Department of Wild Imaginings, now in spectaclar stereo, sponsored by the Adhesives and Sealants Council, suggesting ways to stick things together since the 1800s. Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
