Oh yeah! Now this is a thread for me! 
Intro: I’m in Aix-en-Provence, and I do a lot of workshops throughout France and occasionally elsewhere in Europe.
I’m usually working in art & design schools, and a few select universities. My subject is code-based art, with more and more of an emphasis on hybrid forms, which means that there is a lot of electronics (Arduino/Atmel by preference, sometimes PIC). Currently I use Processing at all levels, and have started this semester with OpenFrameworks as a continuation of Processing. We have three more weeks left in the semester. One student has to finish a floor-projection/tracking system in a few weeks, and we’re using OF + OpenCV for that. The other students are just experimenting with it.
In Aix, I run an “Atelier” which means that our daily job is actually building stuff. From this studio perspective, OpenFrameworks, like Processing, has to be ready enough to make artwork with it, and yet accessible enough for art students. We’re definitely there with Processing, and obviously have a long ways to go with OF, but I can help on that front and have some experience there. Also, Processing got most of it right, so the OF project can blatantly copy some of those ideas.
On May 26th, I’ll be conducting a workshop at the Biennale Puglia 2008 (http://www.bjcem.org/) where I’ll show all the tools I use, including OpenFrameworks.
Next year, I will be conducting a two week intensive training session in Aix with the 1st week dedicated to Processing (beginner > intermediate), and the 2nd week dedicated to OpenFrameworks (intermediate > advanced). I am using the current semester as preparation for that intense session which will be open to a lot of outside participants. I am also experimenting with the current batch of students concerning what sort of materials, examples, methods I can use to get them up to speed.
Finally, there is an important on-line component that I use for support, similar to what ITP http://itp.nyu.edu/physcomp/ and others do. Here are the links, for example, to the class on Processing http://www.ecole-art-aix.fr/rubrique34.html, and all the rest http://www.ecole-art-aix.fr/rubrique11.html. Those should give an idea of what I plan in the future. I will be making a similar on-line tutorial this summer, or at least in time for the two-week session I just mentioned.
