My flatemate moved out and left us with a plethora of leftover art supplies, including several giant pieces of foam-core for which I really have no use.... until last night!
My other flatmate is rather fond of video games, and I'm rather partial to shenanagans, so we decided to put to good use and decorate the room where we're building art kits this year. We shoved about 24 boxes of newsprint next to the wall and I parkour-ed my way to the top. Then, using some handy kendo swords, managed to shove the thing on top of the ventilation shaft.
I'm betting it'll probably still be up next year.
