when I first saw this I was thinking of those hypercolour tshirts that were slightly terndy in the late '80's that changed colour with body heat (or made it obvious you were sweating like a pig).

Anyway, take a look at www.plasticlogic.com who are doing roughly the same thing with regards to moving newspaper pictures / displays.
