Uli's source code is on Github!
So, if any of you are thinking of using my source code, I recommend you head over to my Github page:
Where I will be putting up the newest copies of all my neat open source classes. And to celebrate, I am making them available under a very permissive zlib-style license, which means you can freely use them.
I am planning to make more code available there, and hopefully also documentation and example projects, which are currently missing.
You can also find my Sparkle branch there, which includes lots of neat bugfixes, plus a few other things I wanted to make available.
