As read about in "Rainbow's End - A Novel with One Foot in the Future", by Vernor Vinge, this site is dedicated to the vision of the "epiphany" suit referenced throughout the book.
"In the novel augmented reality is dominant, with humans interacting with virtual overlays of reality almost all of the time. This is accomplished by wearing smart clothing and contact lenses that can overlay and replace what the eye would normally see with computer graphics. " - Wikipedia.
These articles of clothing and contact lenses, are called "wearables".
"He was beginning to feel confident with Epiphany, although he might never be as skillful as kids who grew up wearing." -
"Epiphany Rule Number One, what they pound on in all the instructions: Full access is only for parents and spouses -- and then only if you like to take chances.

The tingle in his fingers was surely his imagination, but now the air between them was full of binding certificates."

Plot Summary: "The novel introduces us to Robert Gu, a man slowly recovering from Alzheimer's disease thanks to advances in medical technology. As his faculties return, Robert (who always has been slightly technophobic) must adapt to a very different world, where almost every object is networked and mediated-reality technology is commonplace. Robert, formerly a world-renowned poet but with a notoriously mean-spirited personality, must also learn how to change and how to rebuild relationships with his estranged family. At the same time, Robert and his granddaughter Miri are drawn into a complex plot involving a traitorous intelligence officer, an intellect of frightening (and possibly superhuman) competence hiding behind an avatar of an anthropomorphic rabbit, and ominous new mind control technology with profound implications."
