"...being predictive, being right about the future, is not the point of any given story or novel. The point is about exploring as wide a range of possibilities as possible."
- Peter Watts

Smart Wallpaper  
  Wallpaper that can sense your mood and provide an appropriate color scheme.  

First they went to Decor Botanicals, where a team of five seniors was developing Smart Wallpaper that would change color on the walls of your room to compliment your mood. This wallpaper - they told Jimmy - had a modified form of Kirilian-energy-sensing algae embedded in it, along with a sublayer of algae nutrients, but there were still some glitches to be fixed. The wallpaper was short-lived in humid weather because it ate up all the nutrients and went grey; also it could not tell the difference between drooling lust and murderous rage, and was likely to turn your wallpaper an erotic pink when what you really needed was a murky, capillary-bursting greenish red.

This also reminds me somewhat of the swibble, from Philip K. Dick's 1955 short story Service Call.

Take a look at the reactive wallpaper from John Shirley's 1985 cyberpunk hit Freezone.
