In case you had a deficiency of QR codes in your life, I present to you my Useless Dice:
“Do you like to play games with dice? Do you find yourself unannoyed with QR codes? Then we have the dice for you! Until you memorize which pattern is which digit, this is guaranteed to require a cameraphone to decode what number you rolled!”
I designed this die on a (particularly sadistic) whim. Because QR Codes are the future. Or something. (Die, QR Codes, die!)
