Ok, I got everything running!
The Processing library is here:
http://interfaze.info/files/syphon/Syphon-0.0.1.zip
However, it only works with the latest revision from Processing trunk 🙂
I also would like to contribute a small ant build file that generates the jsyphon jar file, discarding the test files. You can include it in the syphon repo if you want.
Cheers!
