I played around with Sinatra a bit at RailsConf and there’s a tiny spec of open source code to show for it:

• Bourbon - An extension to Sinatra that adds support for Liquid templates.

• ColorURL - A simple Sinatra application that displays a page in the color of the URL path. It uses the color gem and is deployed on Heroku. [[http://colorurl.heroku.com/mauve](http://colorurl.heroku.com/mauve)]
