Right, you obviously need to build your own turntables. The idea that you'll just find one laying about, especially in a sculpture garden, is absurd. Let's look around and see what you have to work with here. Not a lot. There's sand, there's twigs, there's leaves, and ... no, actually, that's it. You’ve got a dilemma before you. Are you using twigs and do your best to weave them into a set of turntables? Or do you want to shape a set of turntables out of leaves?
