My plan is to create a rotating ballerina from the pictured file I found on Thingiverse. The ballerina part represents my dream career as a child, but the bottom will be a visible gearbox that I will create in SolidWorks representing my current career path.

I like the idea, will it be electric or a wind up?
How will you make it rotate? Will you have a motor? How do you plan to make the gears visible?
