That is exactly what happened.  I talked to the guy who took the picture.  He had set the exposure manually and intended to take a picture without the flash.  He recalls the flash going off accidentally once.

I took my camera out to my driveway and set the exposure to 2 sec, forced the flash on and took a picture of my truck.  After the flash I purposley moved the camera field of view across the street light.  Same exact effect.

There is no question now that the wierd effect is a street light that was acidentally panned across the frame.  

Same street light, different camera, same effect.  There is even a secondary trace that must have something to do with optics or a reflection internal to the camera.  I only panned across the light once.

I think I've wasted enough bandwith of the list by starting this discussion.  I think we should put it to bed before the moderator shuts it down for us!

It's been a fun discussion, but isn't Tesla related at this point.

Thanks,

Curt.

The camera was hand-held, and apparently no attempt was made to keep it
steady.  The exposure time was 1 second.  A lot of territory can be
panned within that duration.  That's why nothing in the background is
visible.  The image of the Tesla coil was frozen by the strobe, because
it was within the range of the strobe, and because it emits no light of
its own.  But the street lights, emitting their own light, are not
frozen, but appear as orange pulsing curvy lines, curves corresponding
to the motion of the hand-held camera.  The light was not bent; rather
the canvas was moved.  You can clearly see that the two dimmer orange
lines have identical geometries, representing two distinct light
sources, both subject to the same motion of the camera.  The bright
orange line is from something closer than the other two, not sure just
how it relates to the others, but it's clearly the same thing.  No
zebras.

Are you proposing that light propagates in some unique manner near Tesla
coils, which is not apparent with the naked eye, but produces bizarre
artifacts on film?  Remarkable that no one has noticed this before!
