I reckon the ability to scurry up walls, gecko style, could be handy. We know how geckos do it: tiny hairs on their feet stick to smooth surfaces. The problem is, the stickiness only really works over small areas up to a few centimetres. Human feet are usually a bit bigger than that.
But now scientists have replicated gecko feet at human scales. They used special springs to stick artificial gecko hairs to foot-sized plates. The springs even out the load across the plate surface, so much bigger creatures can climb walls. Fancy having a go?
