Version 3 of the QR Code (Quick Response Code) uses a
29-by-29 array of black squares on a white background to
encode messages. QR Codes are often scanned by smart
phones for the purpose of linking to a website whose URL
is encoded in the array of black and white squares. In this
case the encoded URL is http://primes.utm.edu/curios/,
the homepage of Prime Curios!.
