slimv.vim - SLIME-like Lisp and Clojure REPL inside Vim with Profiling, Hyperspec, Paredit. Quite interesting, as it is much lighter and simpler to install than Slime or VimClojure or one of the other heavy solutions. And you can simply program Common Lisp or Clojure from within Vim. It is currently only in the "playing around and looking" mode, but it sounds quite interesting.
