Last Friday the Project OpenPTK team (Derrick, Terry and I) did an initial check-in of the source code. You can download the pre-built samples and browse the source code. Details related to the source code can be found on http://www.ohloh.net. Our initial check-in was about 120 files and included over 15,000 lines of code (that's minus blank lines and comments). The Javadocs for the Java API are available on http://www.openptk.org.
