— William Gibson, Neuromancer
Festo, a german corp, has a movie of a really cool hydraulic cyberarm on their site. Its so cool I want one. The movie indicates that the arm has enough tactile response to write on a touchscreen.
I found the link on lo-fi-samurai’s blog, which is very worth the time you spend there. He was the one I stole both the link and the quote from – I only added William Gibsons name and the title of the book.
