irony: this is in fact "against the laws of physics"

- akiselev 8y agoYeah, I think what he means to say is ultra minituarized matrix of billions of high powered phased arrays all synchronized to keep billions of charged aerogel-type mm^2 "pixels" with a different angle of refraction as you rotate it and a different excitation at different ... just make it up as you go along, its decades away at best!
- colordrops 8y agoSounds like you've thought about it though. If we can imagine it, perhaps it's possible. Could anyone have believed that we could control the color of millions of tiny dots on a thin flat surface 100 years ago? My point is that to say that it's against the laws of physics is as ridiculous as my imaginations of what is possible.
