Every time a new version of LT playground gets released I feel like a kid in a candy store, looking for all the cool new stuff Chris and the rest of the team put in :). Awesome work, and it just keeps getting better. To be honest, since there weren't any updates in a while, I started having doubts about whether they'll be able to deliver, but I'm glad to see that the project is alive and well.

Judging by the comments I see that there's a lot of people who haven't yet heard of Light Table, which surprised me a bit because posts about LT frequently hit the front page of HN. If you're one of those people, you should take a look at their kickstarter page: http://www.kickstarter.com/projects/306316578/light-table

Finally, while there's a lot of people bemoaning the fact that some more popular languages (than Clojure) aren't supported out of the box, I, for one, am glad that somebody's developing such an awesome tool with Clojure in mind.
