There are few ways to exercise more fun and more addictive than rock climbing. If you live near an indoor climbing gym, you'd be crazy to not go there for your workouts rather than some generic pumping iron gym. But what if you don't live near one? Well, bring the wall to you!
The Climbstation is a personal rock climbing simulator, providing an "endless" wall for you to climb that keeps you at a safe height while providing you with ever more handholds to go after. Sure, it's crazy expensive and far from practical, but if you've got the scratch and the space you could do a lot worse.
