What do you get if you mate the ultrasonic technology of a sonoluminescence
setup, with the ideas behind a paul and/or penning trap (sorta kinda, also
they're usually electromagnetically based)

I always wanted to build a penning trap and levitate a dust spec in a vacuum
chamber and then using an interferometer and some DSP make a hell of a
seismograph.  I'd probably just end up electrocuted, dust spec penning traps
run a couple hundred volts...
