Functional thinking: Thinking functionally, Part 1 (here, via @planetclojure) -- Just be glad you don't have to write this kind of code...
Clojure Atlas now available: "An experimental visualization of the Clojure language and its standard library" (here, via @cemerick) -- This is an interactive visualization tool for clojure libraries, with the outstanding quality that it is not just a mechanized extraction of metadata and dumping of it into the web, instead, it is properly curated.
Growing so fond of #Clojure that I think of the parens giving my forms a nice hug. (via @carinmeier) -- Aaawww!
I just uploaded a simple tic-tac-toe player in #clojure Simple but beautiful. (here, via @paraseba) --"It was created for a Clojure presentation, where the public knew nothing about Clojure.
