With some jobs, you pretty well know what you'll be doing today, next week, next month and next year. And I guess road liners come into that category. I felt so happy for the guy who did this. There he was anticipating another week shuffling along the gutter, mile after mile of straight lines, and he gets sent here. Lovely curving shapes round the traffic calming, an opportunity to show a bit more flair in his work. I hope he enjoyed laying the lines as much as I admired looking at his efforts. Bridget Riley, eat your heart out.
