Does anyone know how they manage to pack so much information about what's visible from every angle into each spot on the board? This seems like quite a step up

  I was wondering the same. I imagine the material structure is tiny, multifaceted particles that reflect a different colour / value at each angle of incidence. I'm not certain how you'd do that with a realtime display. but if each of those particles had an OLED on each facet it might work. Extraordinarily expensive, mind and even then it's a pretty big if.

    No details of how they do it, but: http://www.zebraimaging.com/html/lighting___display.html http://www.zebraimaging.com/html/lighting___display.html

  You might be thinking of a Rainbow Hologram[0]. The breakthrough here is in production from a virtual scene, not in quality. The "features" of the material in any hologram must be on the order of the wavelength of the light you are using. The image is recorded as an interference pattern of light rays, so good hologram has a resolution of 20-80 nm! There are some images of good holograms at the bottom of [1], and Claus Cohnen gave a good talk about the state of the art at the Chaos Communication Congress last year [2].
