This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Hate to reply on threads from last year, but I had to say that Clojure Atlas is an interesting idea.
What's even more interesting is that during a talk on Clojure pain points Chas Emerick said that you'll HAVE to read the source code eventually ( something about chunked sequines and deaf inlines .) So to make it easier to read through the source, Chas made the Clojure Atlas to visually navigate through not only clojure source but abstract concepts.
Other than that, there are always youtube and infoQ videos.
The Try Clojure site (http://tryclj.com/) has the shortest tutorial I've ever seen but it's a nice online REPL except for a few quirks. I also have a repl on my phone so I can play around with Clojure when I'm bored in long lines or on the toilette.
When all you have is a hammer, everything looks like a thumb.
