For those people in London (England) interested in SICP in Clojure, we are running a monthly study group. Our google groups group is https://groups.google.com/forum/#!forum/sicp-mailonline and the code is at https://github.com/MailOnline/sicp-mailonline (each person has their own branch).
We are just starting Chapter 3 and at the current rate of progress it will be at least a year before we have completed the entire book!
Anyone interested is welcome to join us :-)
