For anyone interested in a bit of background about him and some other indie gaming greats, I highly recommend checking out "Indie Game the Movie" - it's a documentary about the development process of Braid (Jonathan Blow), Fez (Phil Fish), and Super Meat Boy (Edmund McMillen and Tommy Refenes).

At about 10 USD it's a bit steeply priced, but I found it well worthwhile: http://buy.indiegamethemovie.com/
