Hmm..  thermal expansion/contraction dictates that this might be more
difficult than you realize..  unless there's some sort of medium like a hard
rubber in between the upper globe of glass (I assume Pyrex would be the way to
go here) and the metal base..  Anyone still remember the coeffs of expansion
for glass and various metals? Or, instead of mercury, and number of different
weight oils and liquids of varying colors..  maybe to match exteriors?

Heh..  you could have a mini lava lamp effect going in there, just in the heat
conducted from the tranny..
