If you can make anything "look" like something else you have taken the first step for something to be invisible to most people or creatures here on earth. My experience with things from other times and places is that our future has these things and other places have these things and the ability to appear to be something else has always been here on earth through time or space(one or both). So, to think these kinds of things haven't always been here on earth (since before cavemen is to be naive). We are just inventing them now. When did others invent these things before in the past, present or future or other places than earth?
Cuttlefish Influences the Latest Camouflage Technology

The
cuttlefish, otherwise known as the "chameleon of the sea," has the
unique ability to change the color and pattern of its skin to avoid
being hunted by predators.

As these creatures are masters at blending in with their surroundings, researchers at the University
of Illinois at Urbana and the University of Houston in Texas worked to
create a flexible pixelated sheet that can detect light falling upon it
while simultaneously changing colors at the same time.

notes.As octopi and cuttlefish, alike, carry the amazing ability to expand and contract pigment cells located throughout their body, simultaneously changing the color and texture of their skin to mimic the surrounding area, researchers worked to recreate this idea with a synthetic material.
"I think we've put together the key elements that are needed," said lead study author John Rogers, who heads the materials research
group at the University of Illinois at Urbana-Champaign and expert of the Rogers Research Group, via IEEE Spectrum.The researchers worked to develop
a material comprised of stacked and very thin dye layers that are
divided into pixels that are normally black. However, the material can
become transparent when heated."It's nothing close to being ready to deploy
,
in a military setting or anything else," Rogers said, via BBC News.
"It's really a beginning point, to focus on the engineering science
around how you might create systems that have this type of function."With future studies
, researchers hope to bring in more colors to the camouflage mix than just black or white. They also hope for a faster response time in the future.More information regarding the findings can be seen via the Proceedings of the National Academy of Sciences (PNAS).
