In my college room, dressed up and only myself to impress!
The red poster is a chart of traditional Chinese characters for words like "chaos", "bisexual", "orgasm", "taboo", "vampire". I'm learning Mandarin at uni. Although they only teach us simplified characters, this poster proves a hit with my Asian friends who can actually read it.
The poster that appears above me, of "peeling heads", is a print by Escher. I could have gone for the classic stairs one, but a little variety never hurt.
What I'm most proud of is the tie, though. It's perfect for me, and it was just $3 from a second-hand place. What a world.
