i notice in both pictures that there seems to be a form of cloud around
and extending from the sides of the toroid. are these evident in looking
at the coil with the eye? it is interesting that they are seen in the
lighted background pic also, from the looks of it they seem to "twist"
slightly, almost like an ion cloud or like a vortices coming from the
trailing edge of a plane in hard climb?
very interesting.
