This can be done with a vacuum tube tesla coil or a solid state TC
(but very likely not with a standard spark-gap TC). You could also use
a TV flyback instead of a big TC secondary&primary setup (I'm building
one currently,
http://www.hut.fi/~jwagner/tesla/tv-driver/schematics.htm, it works
ok, but the audio section schematic displayed on the page is not quite
up-to-date yet...)



For more of audio response and less of long streamers, see:

Something along the same principles is described in the US patent no.
4,956,577 (inventor is William P. Parker) - you could consider it
luminglass with different electrodes. T.ex. use
