title: How to Implement "Code Bubble" like User Interface?
body: <p>The new <a href="http://www.cs.brown.edu/people/acb/codebubbles_site.htm" rel="nofollow noreferrer">Code Bubble IDE</a> has been in the news. I wonder if there are useful libraries to implement this kind of interface (for other applications)? I prefer java or python. I understand Code Bubble has been implemented on Eclipse. </p>
