On my travels, to Huddersfield on the train during my half term break, i was reading the 'Sun' and found this valentines day advert for Marks and Spencer.
The full advert, QR code bottom left.
The QR code
On this advert was a QR code in the shape of a heart! this has inspired the idea of doing a QR code in a different shape to the typical 'square box'. The colouring of this QR code also stood out to me as it was pink and white rather than black and white.
