On the café wall.

Last Friday (6th February) a small group of us held a Blipmeet at Clementine's Café in Bewdley (Worcs.). Well I was there again this morning - on my own - and (at a different table) I noticed this striated light pattern on the wall adjacent to the flat metal cup sculpture hanging there. I decided to dig out the iPhone again to record it. There were some very subtle rainbow colours in it, not so strongly visible in the image, but there nonetheless. The source for this pattern was the moulded glass lamp holder on another wall behind me, shining transmitted window light through to this wall.
