Imagine if the computations in chips (or CPUs, Computer Processing Units) could be performed at the speed of light instead of electrons. Photonic chips are such devices that use light beams instead of electrons to carry out their computational tasks. Researchers at MIT have made a breakthrough that allows them to make those optical chips using standard microchip manufacturing machinery, with the design of the circuit produced “just like an integrated-circuit person can design a whole microprocessor. Now, you can do an integrated optical circuit.”
Photonic chips “may be the next generation in terms of speed” for communications systems, says Caroline Ross, the Toyota Professor of Materials Science and Engineering at MIT who lead the development.

Biomedical engineers at Toronto’s Holland Bloorview Kids Rehabilitation Hospital have created a Virtual Musical Instrument (VMI) that allows a quadraplegic to play music with slight movements of his head. A computer’s webcam captures his movements, and as his head passes through particular shapes displayed on the screen, different classical music phrases are played.
Researchers at Washington University have embedded micro circuitry into contact lenses that can project images in front of the eyes. The eventuak goal is to embed hundreds more pixels into the flexible lens to allow it to project complex holographic images. Practical uses may include projecting journey directions, a vehicle’s speed, creating a virtual world for video gaming, and providing up-to-date medical information.
Case in point is The Belmonte Castle picture which won a Gold Award at the 2008 

What do you do when the light seemingly does not cooperate and, try as you may, you are unable to get an exposure that will assure a sharp image? Throw the rules out of the window, as Jeff Wignall over at
