The most I've seen a breakout board control is 5 axes. Maybe you could gang up two of them. But you'd still need a separate driver for each motor. If the motion you need is pretty basic, maybe a different kind of motor that's easier to run would work. If you had ten regular DC gearmotors, for instance, connected to a breadboard, it would be pretty simple to give them on and off signals to roughly control the motion of your sculpture.

Interesting idea. I've become so accustomed to working with Steppers I hadn't thought of this. I'm not sure I would be able to get coordinated movement with gear motors but I can certainly see the benefits of the simplicity.
Any off the shelf BOB that I could control a bank of SS relays with? Software?
USB would be nice since parallel ports are going the way of the dodo.

I found this on Amazon.8-Channel 12V Computer USB Control Switch Relay Module Drive-Free Relay Module Plug and Play Suitable for PC Smart Controller.

Does anybody know how to setup a PC to turn relays off and on at different times and durations?

If you were prepared to use Raspberry Pi and the GPIO [output] pins you could control more than 10 relays.

Using this approach, you'd probably need to do some Python or C programming.
