I recall hearing about something along the lines of what Zappo described and am Googling for one. In the meantime, here’s something Google returned that might be of interest: http://www.car-nection.com/cadillacdatabase/dbas_txt/Drm65-66.htm
Nothing for “mood car” but did find mood paint .
This is not the stuff of science fiction or even structural engineering. It’s just paint - the home-improvement staple mixed with a thermochromic carbon-based pigment
that fades as the temperature rises and brightens as it cools. NASA developed the substance as a coating that would warn scientists when a machine was overheating.
Researchers also hoped that the material could be used as an exterior house paint that would darken and absorb heat from sunlight during colder seasons. But the paint
is not UV protected and costs too much to affect energy efficiency.
So, for the moment, it’s just the stuff of art: Jürgen Mayer Hermann, a German artist, mixed the thermosensitive pigment with latex house paint to create his
Housewarming installation. When you touch the wall, the color temporarily fades, leaving a sort of negative shadow. Functional? Perhaps not, but fabulous nonetheless.
Sounds like it still needs some work for any mass-consumer applications.

Thanks Jeff.
I know Yann Saunders (the database guy) pretty well. He’s on the Cadillac Mailing List and I’ve corresponded with him. If you like Cads he’s one of the guys to talk to.
Zap!
