Remember the animals on the Underground - animals that have been "found" in the Tube map. Well, this got regular contributer & commenter Jon Justice thinking about whether you could see anything else in the London Underground map. Letters for example.
He was sitting with a friend on the Tube and she insisted that she could see letters - almost a whole alphabet.
"So we ended up sitting down in the pub trying to trace out the whole alphabet. It's harder than it sounds. As long as you mix upper and lower case, you can get most letters, but some we just couldn't get at all. B, C and O eluded us entirely (at least not without making them huge) and we're not at all happy with A or S and we had to cheat and use the DLR to get a G. The M is pretty ropey too." he said.
I think it's a very good attempt- although I'm surprised they couldn't get a better S! Do you think you could find the missing letters? Or have you seen anything appearing in the Tube map if you stare at it too much?
