I have tried the LightTable and I can run Clojure commands just fine, but I can't figure out how to show a webpage within the IDE and execute ClojureScript commands against the DOM of the webpage interactively.
Update
I will start to make a video series on Clojurescript, which will show how to use LightTable: http://www.youtube.com/watch?v=lX6isnBn6mY
