A team in Singapore have developed an invisibility cloak that can hide goldfish and cats.
I haven't read the link above as it's taking ten minutes to load a page at the moment due to my slow net connection. What you really want for invisibility is a covering with lots of spherical pits in it acting as pinhole camera/projecters. If the covering is rigid, the equivalent of a retina in each pit would detect light and be able to pass it through to a single pixel in a single pit elsewhere through an unchanging link, and that pixel would then emit as much light of the same colours as hit the original. The more pits used, the better the illusion (or un-illusion, in that you wouldn't see it). At a distance, one centimetre might be sufficient pit resolution, and a person could probably be covered adequately with a couple of square metres, so 20,000 pits be required with perhaps a similar number of pixels each. That would require 400 million connections between pixels, although the wiring could obviously be simplified by timesharing the wires. It strikes me that this should really be quite a trivial thing to build these days. David Cooper, Fri, 14th Jun 2013
Yes the invisibility cloaks are actual and real, ( though they do not make people or objects disappear, they bend light ) and they are being used, and developed further, by Defense Research and Development Canada, one of the companies involved with the program, Hyperstealth Biotechnology Corp., the U.K. and the U.S. as far as the owner of the textiles company has commented on.
You guys make it really hard to see the invisible cat when the dropbox is denied and this is my third attempt at a comment because the first two were denied and then was unable to 'Go Back'!! Just let me see the video. Please. amber, Tue, 18th Jun 2013
