I'm working on a Processing book due on this summer. It has a brief section on interfacing Processing with Arduino and I need a nice little photo of an Arduino board to put in the book. If you have one I could use, please write: daniel.shiffman@nyu.edu Happy to give credit of course.
Also, if you want to use the image from the Arduino home page, I know Nick has a high-resolution copy that I'm sure he'd let you use. He's got a contact form on his website: http://www.zambetti.com/contact.php, or message or email me and I'll send you his email address.
