Having waded through masses of literature by theorists with no practical background and a tendency to make mistakes like attributing Star Wars to Steven Spielberg, it is a delight to read a text that is grounded in both experience and solid rhetoric. Lev Manovich writes with clarity, wit and provocative insight - a rare and enjoyable experience for anyone doing serious research in this area. This review is based on the MIT Press version of the text.
