Thanks, Phil - and also for your comment on the Nomadness blog! The best thing about Arduino, I think, is the wildly creative and diverse community... very much in the spirit of what I like to call "gonzo engineering." I have a little rhapsody on that topic over here (especially the first 5 paragraphs):

This is fun; good to be here.
Cheers,
