Indoor rock climbing walls aren't exactly outdoorsy, no matter how much faux-boulder texturing is done to the plastic you're hanging onto. That's why this crazy designer gym in Japan is so awesome — there's no pretense about you climbing around on the side of a mountain when you're perfectly well aware that you're in a building in Tokyo.

So if you visit this Illoiha gym, rather than be faced with a wall full of knobby fake rocks, you'll have the challenge of scaling a wall using picture frames, flower pots, and deer antlers. Frankly, it looks like a load of fun, and I love seeing something that's never really messed around with changed so radically. I'd love to see more gyms using creative design like this. How bout it, Bally's? — Adam Frucci
