I used to do some stuff with pd-extended about eight years ago. I did a quite interesting and rather large project back then but I haven't really touched the language since [although I kept receiving these mails and sometimes I even read them]. I'm thinking of getting back into it, so I have two questions for you:

1. Are there any new libraries (from around 2010 onwards) I should be aware of? Be it because they're useful or cool or your favorite for any reason.

2. What do you think would be good katas for Pd? It doesn't matter if they're very basic.

Thanks!
