That really looks great.
Are you going to use a flat black to offset the shine of the wood? Or, are you going to go with a gloss to match the gloss and use the light color of the wood to make the turnings stand out?
I am another one voting for slowly rotating when/if you can in the future. I would judge 1 to 3 rpm...give them time to look at any one piece. Pique their curiosity as the next turnings come into view. They have feet; they can move a bit if they want so see it a little faster.
If there was, say a 5/8", shaft up through the center, with a large pulley (even a plywood disk with a groove) on the bottom with a belt going to a motor (sitting shaft straight up) with a small pulley you could probably make the unit quite inexpensively. Ideas: old washing machine motor, small pulley on motor from whatever (or give up and buy one), Old washing machines had a fairly large pulley on them; think junk yard, appliance dealer junk, make your own of laminated wood with 1/2 round or "V" groove large pulley???? Remember, think outside of the box.
Your library will have a reference book or so showing how to compute speeds using different size pulleys. Or, as Glenn is always telling me, "Google is your friend." If you cannot find the info elsewhere, try the reference section of the library or where they have "reference" type catalogs for rigging, or other applications that use pulleys.

First of all you have to be smarter than the machine.
