Nice Part Use (NPU)

A Nice Part Use (NPU) is the use of a LEGO part in an unexpected way. I do not have many examples that I used myself that have not been already done before, but if I end up doing any never-before-seen (or me being the first) NPUs in my MOCs I will post them here. I personally would attempt to NPU some parts that usually have very little use other than the use they are used for, or parts that are sitting in my LEGO bins not seeing any use and perhaps I could build something original out of those parts (but most likely spaceship-related). My nephews tend to do NPUs out of LEGO brick separators.
