Just read an article in Popular Science today about a fashion designer who has used biologically GROWN fabric that is actually tougher (and lighter) than leather. If draped over a form while still wet , say like a mannequin, it "knits together" at the seams.
I mean ya gotta admit, this stuff is weird, but we may see some of it showing up in backpacking gear in a few years, or in shoes or clothes.
(No I have NOT been smoking anything today!)
P.S. Is the nest skin for anthropomorphic robots? Eeeeewwww!
