Permutaion City has some brilliant scnearios too! The thing starts out with a character that wakes up as a digital copy of himself in a tangible 3D world with all five his senses functioning and he can even conjure up a menu out of empty air to transform his surroundings or call up the non-digital version of himself. I've never read it but I've been reading about it and the ideas that shaped it a lot lately. Just outstanding.
