QR code

went out to brunch this morning then spent most of the rest of the day tidying up at home. We were supposed to be going to an airshow at  Old Warden but it was cancelled in view of the rather soggy airfield and the weather. I only took one photo, of the cafe door as I'd forgotten to take any inside, so here it is given an 'extrude' filter in PS.  My niece did some research into QR codes as part of her university work a few years back whenhardly anyone was using them and they really didn't know what use to put them to. Seem to have found a good use for them now!
