Just use a small low voltage DC motor running on a small gell cell
battery. It's isolated from ground and shielded by the toroid so no
harmful currents.
We do this same effect with our vertical "Eye of Thor" which arcs
across a glass plate 7 feet in dia. The glass aids in tracking
especially if you spray some water on it prior to operation. You
could make a 2-3 foot dia version of this for a small or med nst powered coil.

WOW that is awesome!!! How does a motor sitting on top of the toroid
not get fried?"
How about just an oversize "Z" spinner - don't know if there's
any official name but Z-shaped gadget with sharp ends balanced on a
pivot in the center? Biggest one I've made is about 4" but gives
similar effects on a small scale. Maybe a much bigger one on a
high-powered coil would also work. The pictures are great!
