A new type of hologram harnesses a quantum effect and uses ordinary light to make 3-D still images. Future 3-D displays based on this technology would have no need for 3-D glasses or special screens.
The technique is based on the behavior of free electrons on a metal surface, according to researchers at the RIKEN Institute in Japan.
Long gone are the days of pushing plastic armies around hand-drawn maps. Today's military planners deserve technology of the future, and that means nothing less than 3-D holograms will do. Luckily, we have DARPA, ever-ready to step in with a solution.
Oliver Kreylos, the Kinect-hacking pioneer who you might remember from our earlier roundups, can't seem to stop pushing the Kinect's 3-D holographic capabilities. This newest hack involves two Kinect sensors, a virtual office, and, improbably, a Nintendo Wii controller, but the end result is pretty amazing: Holographic video chat in full 3-D.
A holographic contact lens sees trouble brewing inside the body

Kaleidoscopic holograms like the ones stamped on your credit cards could soon wind up in the eyes of diabetics. Researchers at Smart Holograms in Cambridge, England, have devised a contact lens that changes shape in response to glucose found in tears—a direct indicator of blood sugar.
