The code is available here:�http://ss3.gemstone.com/ss/Esse.html. I'm not sure this is the final version, but one of the most "recent" ones. Also, I've attached a .rar file with results Pavel submitted to Google (in case, you can't access them from their site).

There are two major problems with the project.

1. The code quality is really low. I think, it's not Smalltalk-ish code at all. Unfortunately, I didn't manage to control code in 2012, and was able to manage it only in a fraction of how I would like it to be in 2013. It's really hard to do in GSoC (as it is more feature-oriented and focused on "external" result, not internal quality), but I hope now I understand how to do it (in case I'll take part as tutor, of course).

2. The project suffers from using "conventional" (old) graphics engine. This problem was addressed by a student in one of the thesis works I gave last year, but with only partial success. And worse, for some reasons, the student is not available right now and I can't get the code she wrote. This is for the first time and really frustrating me :(

I still think the topic is really important, can be widely used in both applications and development process itself to the advantage of Pharo, and is really interesting.
