Years ago I saw an interview with a futurist that mentioned the following:

"One day, your kids will go to the toy store and get a sheet of stickers. Each sticker is actually a camera with an IPv6 address. That means they can put a sticker somewhere, go and point a browser at that address and see a live camera feed.

I should point out: all of the technology to do this already exists, it just hasn't gotten cheap enough to mass market. When economies of scale do kick in, society is going to have to deal with a dramatic change in what they think 'physical privacy' means."

Maybe it's possible but i can't i seem to think of an energy harvesting Method that would fit that system without direct sunlight.

I'm very skeptical this technology already exists. Maybe if you vastly change the meaning of "sticker"

And when you scratch the stickers they smell like strawberry.
