Square is a sweet-looking little tool for taking credit card payments with your iPhone. They’ve been all over the design blogs lately for their well-designed product site and product demo video, which is the work of the brilliant @lonelysandwich.

I agree, “The Square demo video is everything a demo video should be: clear, concise, informative, funny, good-looking and memorable. Come to think of it, that’s what we should all strive to be.”
