Chameleon paint for your car. And shark skin paint!

Here

Interesting, and freaky at the same time.

So no more waxing?

Isn’t shark skin smooth in one direction and very rough in the other - due to many tiny overlapping scales? (i.e. not really much like sandpaper at all).

And conductive paint? Ummm… that’s been around for years - I have a really good idea for a circular, rolling object that will revolutionise the way we move things about.
