Hey all,
     I stumbled across a web page advertising a square Tesla coil, the 
secondary was round, but it got me thinking.  Would anything other than a 
round secondary function properly, such as a square, or an ellipse, or an 
octagon, or even something exotic like a star shape (if one was tricky, he 
could interweave the windings in the same manner one draws a 5 point star 
without lifting a pen, around 5 vertical poles)?  I would imagine breakout 
would occur at any "corners" as viewed from above, not to mention it would 
be a pain to construct.  Just musing.

Tesla wound cone shaped coils. Though I do not see a square one working to 
well.

Makes me wonder really about the primary coil also. 
http://www.future-technologies.co.uk/IMPULSE/hotstreamer/room/img76.gif  I 
tried a oval type one and it seemed to work really well. In fact where the 2 
cut out circles are in the center, one coil was placed over the hole so the 
secondary was not in the center at all. It seemed to tune a lot better than 
my  circular primary coils. I never investigated it, though I do not think 
anyone else has either.
