NaviLens EMPOWERING the visually impaired
Using some sort of color 2D barcode, similar to QRcodes. Similar to Microsoft Tag/HCCB color 2D barcodes (though HCCB used triangles instead of squares, and had some sort of monochrome compatibility mode?)

Optics InfoBase: Optica - Flexible photonic metastructures for tunable coloration
Interesting method for structured color changing. If they can get MEMS actuators to flex the silicone substrate on demand, you have a real chameleon skin cloak.

Bioinspired fibers change color when stretched — Harvard School of Engineering and Applied Sciences
Interesting photonic fiber research, which resembles dichroic materials, but because it is stretchable, allows active changing of the color by adjusting the bandgap. Possible uses in smart cloth showing deformation damage, or as a possible active camouflage textile system.

B-Core Inc.|Color Bit Code
This could be used as an alternative to active RFID tags. The basic system triggers on an IR code from the reader, then burst sends the Opto-Chrono code output. If you could get really low power, it may be possible to make a form of passive tag , which uses an IR solar cell to gather power outputted by the reader (primary power IR lamp at constant power output , and a secondary comms IR at a different frequency) in a capacitor for operation.

B-Core Inc.|Color Bit Code
Saw the demo of this at RIDEX 2010. 2 megapixel image machine vision software scanning to locate and extract the color barcodes is near realtime (demonstrated as an iPhone app that could pick up multiple codes in the image, even spiral and distorted codes). Other neat features are that it could be printed directly on the edge of paper/objects (normal barcodes need a clean white area surrounding the barcode). 3M is using this on reflective backed labels, allowing barcode capture using a special camera from over 30m away.
