When I left student accommodation, I'd collected a large amount of porn that I couldn't sneak home, I stashed it over several cross sections of floating ceiling tiles and like to think it's still sitting there today.

Probably purloined by maintenance men a while ago

My mate moved in with his GF and asked me to store his porn collection. Around 5 boxes of magazines. I briefly entertained the thought of pasting the pages over all my walls, floors and ceilings to be a Brighton Festival Open Art House, but in the end, I just left them down there when we moved out.
