Speed of Light – Copenhagen Metro A collection inspired on the fast moving NFT world. Such a sense of speed in these images, was created using specialist camera equipment and techniques by artist Tony Sellen. Spending over a week riding around the metro network in the Danish Capital Copenhagen, Tony picked the best railway infrastructure locations to create these impressive artworks. Københavns Metro has a system stretching over 38km, with 4 lines and 39 stations. Using driverless trains gave the opportunity to see out the front or rear of the trains, helping create this art collection.
