Couldn't say; I haven't been there. (If you see videos more recent than that one, since H4K became sort-of-famous, he actually outfitted his playground with all sorts of interesting stuff that wasn't originally there.)

But a pull up bar (or a swing set) and parallel bars (or any two parallel objects you can hold onto) are enough to do a variety of interesting exercises. (BTW, I assume you know that if you take the Iron Gym you already have and put it on the floor, you can actually use it to do triceps dips as well.)
