There's also http://ecmendenhall.github.io/sicpclojure/pages/contents.htm... which is an actual translation of the book into Clojure, currently up to chapter 2.1.4.

And the ill-fated sicpinclojure.com site, which looked beautiful and had such great promise, but mysteriously stalled and died.

Looks like vqc below has done quite a few of the exercises. Nice.

Tommy Hall's SICP Distilled seems like the best shot at a complete book now. It's running a bit behind schedule but appears to be in the home stretch. We'll see!
