"Is that a way to produce a decent sized low blanket of fog?"
Exactly. Found them on Amazon under "Ultrasonic Mist Maker" for less than ten dollars. Submerged two or so inches (5 cm), they'll churn up a nice thick fog at 24 volts. They create what looks like a drop of water hitting the surface, but it's static, and the fog bubbles up from underneath. I'll run one of them at 12 v to chase off the dog, but it doesn't seem to bother them if it's submerged.
It sounds like you have a great display! A neighbor takes his chain off his saw and runs it.
