Greeble



Greebles, also greeblies (singular: greebly), or "nurnies", are parts harvested from plastic modeling kits to be applied to an original model as a detail element. The practice of using parts in this manner is called "kitbashing".

Etymology
The term "greeblies" was first used by effects artists at Industrial Light & Magic in the 1970s to refer to small details added to models. According to model designer and fabricator Adam Savage, George Lucas, Industrial Light & Magic's founder, coined the term "greeblies".

Ron Thornton is widely believed to have coined the term "nurnies" referring to CGI technical detail that his company Foundation Imaging produced for the Babylon 5 series, while the model-making team of 2001: A Space Odyssey referred to them as "wiggets".
