Not strictly on-subject but perhaps of interest:  That was an example of
my failed-product, "Neon Bubbles" (TM) (and formerly (R) except that I've
abandoned that).  It's a standing wave of ionization produced by choosing
the appropriate audio-range frequency of H.V. excitation and then very
precisely controlling the symmetry of the applied wave.  I've had a
number of patents on it, including even a Japanese one, but I've been
abandoning them also because I don't want to continue paying the
"maintenance" fees.

My U.S. patent on that is #4,862,042; it can be found via
http://patents.ibm-dot-com/. Anyone seriously interested in more
details...contact me off-List.

Unhappily, the electronic "transformer" that powered the neon column
became damaged, evidently by the nearby high EM fields from the Tesla
coils, so I am having to fix that.

As to my Entertainment Machine (a.k.a. Tesla coil) itself, see my prior
postings on the List for my comments on that and my offer of
documentation.
