My #chipofthemonth for December is this little analog XYZ color sensor chippy, AMS/Osram AS73210, just mostly because it looks really neat. The thing is basically just an array of parallel-connected photodiodes with thin-film interference filters on top. The XYZ color space is used professionally because it approximates the receptor response in human color perception better than e.g. sRGB.
Alas, this chip is obsolete in favor of newer offerings of AMS that have digital readout.
