We just got a note from Mark Lukas about the release of their book Prototyping Interfaces that teaches and showcases how to build interactive things with vvvv and Arduino. They used lots of Fritzing sketches to illustrate their examples. A really nice idea is that they turned the book cover into a capacitive sensor.
It’s all in German, but I assume an English version will follow soon.
