Member funnypolynomial built a very simple, heat driven motor that sits atop an LCD monitor bezel. It’s actual a revision of an earlier design for use with CRTs -
The original Monitor Spinner did its thing on a giant CRT and was prone to falling off, especially if I turned on the fan in my cube. I was pleasantly surprised when I got my flat LCD monitors and found they still put out enough heat to make it spin. I decided to make a second version, less susceptable to breezes.
