Been having an enjoyable half an hour messing around with the QR code generator: the trouble is that my small phone app cannot handle anything too complicated - William Shakespeare and John Donne were both out - or in colour.
Nice if it could.
Plus the qrcode generators themselves have a word limit too - so bye bye Elizabeth Bishop.
The final solution for your delectation is a riddle poem in QRcode. A riddle within a code. As 3D as I can get so far. Enjoy.
