[Image: "Above Ground" by Nils Norman, commissioned by Platform for Art for Transport for London; view it as a 2.6MB PDF].A recent post from the BLDG blog was sent my way by a good friend. Seems like Nils Norman created the above poster depicting alternative visions of the London subway system in 2050. The poster was then intermingled with the "...mobile phone advertisements, travel insurance offers, and posters for English-language schools." that normally adorn The Tube. Steve Lambert & Packard Jennings did something very similar in 2007 for San Francisco. Both projects are a wonderful escape from the typical mind altering brand imagery you are normally presented with on your way to work.
