1. Tottenham Court Road — the famous mosaics of Eduardo Paolozzi, which include the Hubble Space Telescope.
2. Warren Street — hence the labyrinth. One of many site-specific patterns on the Victoria line.
3. South Kensington. The lemur references the animal forms carved into the architecture of the nearby Natural History Museum.
4. Stockwell. Another Victoria line pattern, referencing the old Swan pub across the road from the station.
5. Hampstead. Curiously, the name Heath Street was only ever proposed and never officially used — but there it is in large letters on the platforms.
6. Green Park. The long tunnel between the Jubilee and Piccadilly lines uses grey and blue tiles whose relative proportion changes, to show which line you're closest too.
7. Vauxhall. Yet another Victoria line site-specific image, this time remembering Vauxhall Pleasure Gardens.
8. Aldgate. No story here, we just like the unusual colour combination.
9. Holloway Road.
10. Upminster Bridge. The reversed swastika was once a popular design element. This one was installed in the early 30s, just before the Nazis besmirched the symbol forever.
11. Maida Vale.
There are many other examples out there. What's your favourite?
