Currently, my decorations include:
The Poker Chips from Fallout: New Vegas, custom framed with felt. I still want to distress the felt, maybe light it on fire. haha
Club Nintendo's Twilight Princess poster
Club Nintendo's Super Mario poster
Also, I have the Lithograph of Old Snake, that came with the MGS4 Limited Edition guide (I think) and an autographed Luxodon Warhammer MTG card. The card is the Foiled version and I got during at the MTG Grand Prix sealed tournament in Columbus, Oh, the artist happened to be at the event, so I got it signed. Other than that, I have a couple of my paintings hanging on the wall, one of which is visible in the
Game Room thread.
