Yes, lots of fun, but some points to remember:

It takes lots of power, and for every degree one side gets colder, the other
side gets hotter + power losses.  So to get a low-temperature, you need to cool
the hot side.  

A long time ago (early 80's), I did some neuropharmacological research which
involved cooling rat spinal cords in order to preferentially inhibit some spinal
tracts.  We had a 12V 10A power supply, and used performed cooling in the form
of continuous water through a radiator on the hot-side.  As an aside, we also
tried using liquid freon to cool a silver probe tip as as the freon evaporated.

Leica Cryostats use a Peltier device for frozen sectioning.

So when you were done, did the rats write better or worse C++ code?
