How to implement & ldquo; Bubble code & rdquo; like the user interface?


The new Code Bubble IDE 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.

It looks more like it's implemented in Squeak Smalltalk using it's interface parts as building blocks and Eclipse as back-end.

You can use some sort of good custom drawing library like Piccolo to build your own blocks and connected them together.
