free book on aesthetics of video games

If writing about music is like dancing about architecture, then perhaps writing about video games is like meditating about explosions.

Nonetheless, Steve Poole is giving away his book Trigger Happy: the Inner Life of Video Games for free as a PDF.

He describes it as "a book about the aesthetics of videogames — what they share with cinema, the history of painting, or literature; and what makes them different, in terms of form, psychology and semiotics."

I checked it out from a library once after reading Earnest Adam's article the game designer's library.
