This is a themed contest, please do NOT edit the themepost.
We pass them all the time without a second thought: Non-descript doorways, with no markings. They often blend into the wall, and we just ignore them, assuming they're electrical closets, or fire exits. But of course, that's what they want you to think. Who knows what's really behind them? A hip, ultra-secret dance club? A ninja training school? Caritas? Neverwhere?
In this contest, show us what's lurking behind those plain doors.
Have fun, be creative, follow the guidelines please, and be careful to avoid using cliches. You will have 48 hours to submit so make your entry count!
