There are a lot of ways to show off your geek pride. You can deck out your house to look like the bridge of the Enterprise, pimp your ride to look like the Batmobile, or wear a belt that has a mouse for a buckle. One of these I’ve done, the other I wouldn’t do because of my love for Star Wars, and the third just seems silly.
If you don’t mind people looking at your pants with a weird expression, then by all means, get one of these Mac Pro Mouse Belt Buckles. It’s only $22, and while the mouse looks sleek on your desk, it’s not quite as appealing while holding your pants up. They offer three different Mac mice, and one Compaq buckle that is just plain ugly.
