Disney Channel has been featuring animated Tesla Coils all over the place for "October Takeover". There are bipolar sparks between two torroids on towers and unipolar sparks in another shot. All done digital (anyone know by whom?).
Very interesting though in the animation, the sparks contain both sparks and a bluish purple "effluve" accompanying them, as well as branching brush discharges issueing from both terminals on occasion where the discharge isn't bridging the gap completely...(!) Someone did a nice job and some research for those quick blips...
These are typically shown in my area between Hannah Montana
and Wizards Of Waverly Place
episodes...
