Need a spinning crown

[simsmj]

Drifter, the crown is a lot less complex than at first sight. It is simply a handful of thin rings arranged in a pile. The lower part is a complete ring, the middle parts are clones of the complete ring, with symmetrical sections removed, and the gems are pixel-sized points set on the rim of the original ring. Each ring is raised or lowered using ripple animation along the z-axis.

You can see this most easily by loading up the Crown.x3d file and with no cursor enabled, just set the extrusion to 1, and the bevels to none.
