SICP is such a fantastic book.

I've been working through it using Clojure rather than Scheme and loving it, I've been a developer for around 15 years and I'm still learning stuff from this wonderful book.

I'd recommend it to every developer out there who hasn't worked through it with some dialect of Lisp / Scheme.

Agreed. Obviously I shouldn't have been surprised, but it still amazes me how pertinent it is, 30+ years after it was written.
