In other amazing news, researchers from Harvard have generalized the laws of reflection and refraction:

"By incorporating a gradient of phase discontinuities across the interface [of a boundary between surfaces, such as the glass of a mirror and the air - RH], the laws of reflection and refraction become designer laws, and a panoply of new phenomena appear,"says Zeno Gaburro, a visiting scholar in Capasso's group who was co-principal investigator for this work. "The reflected beam can bounce backward instead of forward. You can create negative refraction. There is a new angle of total internal reflection."

Also, Korean researchers have made 3D OLEDs that have tiny prisms that direct different light to different eyes.  That would be much easier to do with the knowledge gained from the Harvard research above, and could be done at the nanoscale.  Then perhaps we could build a quCPU from those, and not have to cool the quCPU down to superconducting temperatures.

 

lets talk in 500 years, seriously
