"Location aware works do the same but take spatial and navigational relationships outside the almost purely mental space of the computer and posit them in the living city, which has the effect of expanding the way the reader can be engaged in the work. The reader is pulled back into the world, into physical space, and away from the screen."
[edit] while not "hi-tech" per se... it's an interesting intermingling and usage of the hi-tech.
