    Important enough to warrant an article in Wikipedia...

    This is one I made. I copied the dimensions from one I got at the Craftsmanship Museum in Carlsbad.

    (And yes, I do have a drawing.)

    Thanks for the drawing, but you need two components. Is that part you made the base and you use a coin or similar as the spinning disk?

    The part I made (and in the drawing) is the Euler's Disk. The video shows a disk spinning on a parabolic mirror, which makes it spin a bit better than if it was on a flat surface. With the heft of my piece, I am leery of using a glass mirror.
