My husband just showed me the video on Boingboing and I WANT ONE!!! This is just amazingly cool.

Though I still don't completely understand it, it's so amazing.

The rings are caused by the electrons jumping between different charge depths , so the resulting image is rippled? In other words, if you look at this shock fossil from the side, do the ring areas appear to be standing away from the plane of the main design?

Right. The "tracks" jump between the planes that had contained the two charge layers.
I just uploaded a photo of the edge view of this piece, and also a stereo view of the second version of this piece I irradiated last Fall.

The rings are formed because there are two charge layers at different depths, formed in complementary "bullseye" regions. When triggered, the figure sparks over between the overlapping layers, forming the rings.

The rings are formed by a pair of masks made in complementary bullseye patterns and placed on both sides of the slab. The slab is double-exposed to the electron beam with the energy set to deposit a shallow charge layer. When it is triggered, the charge layers spark across to each other and make the ring pattern at two different depths.
