From liquid smooth through crusty and tatty to razor sharp, the range of textures I spotted on my walk along Swansea canal was wide,  to say nothing of the colour and pattern, light and shade that created a natural art exhibition for me.

The water of the canal may have reflected the colour in the sky on this beautiful morning, but it certainly did not reflect the texture of the barbed wire fence round the Mond Nickel Works.

And there was pattern to be seen in the reflection of light from the water under one of the bridges and a very crusty texture on the pipe structures also crossing the canal.
