Tmpltr - jsFiddle clone for realtime JSON templating (rocktronica.github.com)

Thanks for throwing the time behind this. I recently began checking out various JS templating engines and it's cool to be able to mess with Mustache templates in the browser.

Very cool, how long did it take you to build this?

Very nice job! I've been wanting something like this for a while now and I didn't even realize it. How about support for Handlebars? =)

It would be awesome to have handlebars support.
