Here's another shot taken during my lunch trip to Excel / Custom House. It's the non-slip surface that lines the edge of the Docklands Lightrail train platform. I got bored while waiting for the train to come, and quite liked the repeating pattern on the floor. Unfortunately, there's sand in the grooves - I wonder if the pattern would have been better presented without them. What do you think?

Update: Sorry I've not been posting for a few days. I've got 3 important financial exams next week (1 on Monday, 2 on Thursday), so things are a bit tight around here. In the mean time, I am still answering emails and providing some support in the Shutterchance forums.
