Think Geek has created an awesome set of Super Mario Bros. vinyl wall decals. Turn your home or office into the game level of your dreams. Because they are restickable they are perfect for decorating walls you can't paint. They are pretty pricey at $70, but they look to be very high quality.
The classic Super Mario Bros. is a game I remember vividly from my childhood. For years I thought I had terrible hand-eye coordination because my younger brother was so good at it. Well, it turns out I'm an okay gamer, but my brother was a freak of nature with mad game skills.
