Playground mosaics

You may remember that last year I showed how the children's playground in Saltaire had been revamped.  It was a beneficiary of money that was earmarked for community projects, from the sale of Leeds-Bradford Airport to a private operator.  The new playground seems to have been welcomed by the local kids.  It is especially popular with mums of very young children, as there is a part specially for the little ones, and the mums can sit on the seats and chat while the kids play.  There is a winding path through the centre from one side to the other and at intervals there are squares of colourful ceramic mosiacs, which on close inspection are rather attractive.  Oldies like me are not supposed to enter the playgound (unless accompanied by a child under 14) and, since I don't yet have a tame grandchild, I had to sneak in when no-one (appeared to be) looking, to get these photos.  The top one is a mosaic of several of the designs and the lower picture is a close up of just one of them.

Study them closely...the more you look, the more you'll see.... animals and plants, Salts Mill, the New Mill (or maybe it's the Victoria Hall tower?), the Church, houses.....  They'd make a good project for a 'brass rubbing' technique, I would think.
