New methods for producing color holographic video are here, and they could lead to cheaper, higher res and more energy efficient TVs. Daniel Smalley, a researcher at MIT, built a holographic display with about the same resolution as a standard-definition TV, which is able to depict motion because it updates its image 30 times a second. The display is run by an optical chip that Smalley made in his lab for about $10.
