Savu, a Python IDE for beginning programmers. A team of six undergraduate students worked for 20 weeks to develop a beginner's IDE that could function as an introduction to IDEs for beginning CS students at Carleton College. It hopes to marry the low learning curve of the standard text editors in use at Carleton (TextWrangler, Sublime Text 2) with a few of the advanced features introduced by IDEs like Eclipse.
Originally hosted and developed on Assembla.
Built on the back of RText.
