I could imagine that 3D printing could be scaled up in speeds of "write-unwrite" to 60 hz, which would offer a 3D video . Materials are made with a compression algorithm to simplify background info, concentrating on active elements which would require the most data. This could allow a "circular fishtank" arcitechure to upcoming television...

A change in opacity and color ( variable cross-linking) could be effected in certain areas of a gel that un-links spontaneously (un-writes) at a high rate, certain primary colors being stimulated by 3 invisible lasers. In this, there is less info required as un-writing is automatic and each completed scan offers a brief, single (3D) field at a normal 60hz refresh rate. Allowing lasers to stimulate certain proximate points would offer an addition of primary colors into a full range. Each axis would need a laser for each primary color, with a total of 9, with a requirement of all three lasers to converge in order to complete an output (cross linking) at a certain point within the gel. The gel would have to be back-lit and would be a passive display, similar to a LCD of today.
