Has anyone tried something like this?
I had a thought of setting a group up for a scare, building anticipation, lead them to a drop window, and BAM, window drops to reveal a not so scary scare. Maybe a picture of the thing they were dreading. They laugh, thinking that was it, what a lame scare, when WHAMMO, the 2nd panel in the same place drops with the real scare.
The TL;DR version: two panels in a drop window, dropping one at a time. Feasible? Pointless?
