We also visited London during our vacation. Mid-way through the trip I found myself needing to wash a load of clothes so I went to a nearby laundromat. When I entered the laundromat I was surprised and delighted to find original artwork on the wall featuring chickens and ducks, which included instructions for how to use the washers and driers. Very whimsical and also quite clever. Art is everywhere, you just have to look for it. Here are some pictures of the artwork.
