As for copper, the decline in price is probably a good indicator of the strength of the economy and may point to a double dip recession.
There are over 4,000 colors available AND a couple of dozen gray scale possibilities.
So, it comes out on t-shirts, only it'd be neat to use this on a complete man's dress suit.
Every day you'd change the style, the weave, the woof, the warp, the bricabac here and there (buttons e.g.).
The possibilities are endless.
I'd give up investing in clothing manufacturers who fail to make use of e-ink (and equivalent processes).
Do you have any idea what this does to manufacturers of pigments and paint?
It's over guys. That's a multi tens of billions of dollar industry right down the tubes just like that. Plus, there will be preferred weaves to use as a base for E-ink ~ probably a lot more like Tyvek than cloth of course.
Copper plays less of a part in this next stage of computerization of clothing ~ dump copper fast!
