A dual concentric magnetically driven circular Jacobs ladder. The sparks form in one spot but rotate due to the magnetic field.

High voltage halo effects are done with a long exposure of a rotating spark with a colour filter.
Here are some of the effects that are produced by long exposures in a similar manner to the Eye of Sauron effect but not using a Tesla coil.
The photo above shows the “Sombrero” . Well it was meant to be a crown really. Note the reflection in the stainless steel ball which shows the sombrero as well as the flash and my wife and son operating the equipment.
Note that as in all my photos there is no “photoshopping”. The pictures are all single shots and effects are produced with long exposures. Here’s how this one is done:
The HV supply I wired to a rotating setup that holds the electrodes.
The electrodes which will rotate around the ball (or my head) and on a long exposure with appropriate orange filter which is removed before a flash to give “normal” lighting for my head.
The photo above shows the effect off a higher current changing the bright sparks into a flaming arc. I should add that the whole sensation is a bit strange. The ionic wind and charge accumulation on my hair means I can feel exactly where the electrode is.
The photo above shows an ‘electric kris’. The kris is an Indonesian curved dagger.

This was just another quick demo of a comparison between neon and fluoro tubes for Tesla coils.
Above shows a similar length neon and a fluorescent tube with ends connected. The electrode end has been made identical by using same sized electrodes. One has to bring the neon much closer to fire it. Of course the color is much nicer…
Ok, I reckon that there is not enough ingenuity and resourcefulness going on in budget coiling these days.
