Round in circles

We spotted this mosaic on the street corner as we made our way from the museum to the park to search a suitable scene to post today. We had enquired about the reason behind the name of our blip of 4th February and had learned that there is indeed a connection with Bletchley Park. The new houses are built on the site of a now demolished factory (Chapmans) that used to make cardbord boxes. However, during the war they reduced the capacity for manufacturing cardbord boxes and concentrated on making parts for radar, radio, and (as we suspected) the Ultra decoding machine at Bletchley Park.
We did go to the park and took several shots that we will have to retake another day as we settled on this one. It seems to represent going round in circles as many of the decoders must have felt they were doing when faced with some of the intricate codes they had to decipher.
