These are a couple shots of the skeleton jungle gym created by artist Peter Riss and on display in the backyard of the Heilig-Kreuz church in Munich, Germany. I don't think it's made from real bones though. I also don't think you're supposed to climb on it. I doubt those bones could support my weight anyways. Hell, my own bones can barely support my weight. I need to go on a diet is what I'm saying.
Keep going for one more shot.
