All,
Let me be bold and say that the first photo incorporates an optically
clear medium on the top surface of the chip such that when photons are
emitted out the top surface. They exit the IC - into the optical
medium. Then upon encountering the air/optical medium interface they
are totally [by design/desire] reflected back into the optical medium
and thereby optically coupled into a nearby photo-receptive portion of
the IC without the requirement for a physical trace on the chip.
The second shot appears to be of a diced wafer - active circuitry and
bond pads "Up". Being a diced wafer, there are no bond wires shown,
etc.
If it were a normal 'flip-chip' all we would see is the bare silicon on
the back-side - as the 'good' side would be down.
I am still having a problem wrapping my head around these and the very
first photo, although the first one also seems to have optical qualities
about it.
Ingemar - are we going to have to shoot you if you tell us what it is?

Mornin' all Ya'll!
Inge sent me two more pictures. Took me a while to post them this
morning as we lost phase "A" of our three phase power into the building
this morning. Been running around throwing breakers and stuff. Got the
power back and now everything is back to normal.
Anywho, here's Inge's pictures:

Obviously these are pictures of some sort of Massively Parallel
Processing computer, but what? It's not a Cray...
Inge, was the very first picture some sort of liquid cooling chamber for
the core?
