QR in Edinburgh Gardens, a photo by Hecuba's Story on Flickr.
I am constantly amazed at the places I find QR codes. I found this one on a morning walk through Edinburgh Gardens in North Fitzroy. I also love the Lort Smith Animal Hospital one that I often see on a bin in Darling Gardens, Clifton Hill.
When I was travelling in Greece, I snapped one on a tram stop and posted it to Flickr. Next thing I knew I was being invited to join the Flickr QR codes in the wild group and post there. Check it out if you are interested in the use of QR codes.
