Want to make endless loops and turns and bends and ramps of wire? Take a long piece of wire, bend it into a “U” at one end, and how you’re started! Just, you know, bend it some more. Or, really, if you’re into minimalism, I guess you could just go with what we have here and call it good. I tend to complicate things a bit, though. I’m weird like that.
