I live in a one bedroom apartment with my fiance, so the stuff we have on the wall is shared.

In the livingroom we have a white board, a cork board, a Simpsons wall calendar, various framed photos, two wall shelves covered in my anime figures (gashapon, kubricks) and a few other similar things, and my framed Joker and Harley Quinn poster. There's also a Pennywise poster by the door.

In the dining room (which is actually not a different room) there's a shelf-thing with my mini-dictionaries, an octopus plush, and the apple from the Snow White ride at Disneyland, along with a Halo 2 wall calendar, a wall clock, and a framed Invader Zim poster.

The kitchen has Chinese lanterns, but those are technically hanging from the ceiling.

In the bedroom is a couple framed photos, and a framed ToeJam and Earl poster that came with the original SEGA Genesis game.

That's about it. I have a ton of posters but they're all stored away at my mom's house.
