The German artist Markus Linnenbrink created an incredibly colorful journey in a tunnel in a prison in Duesseldorf (Germany), where visitors pass through to see their friends and loved ones.
If you take a took at the images you get a sense of the space. Imagine what the tunnel must have been like before the transformation: a claustrophobic, long winding space with monochrome white walls and those ultra functional yet hideous neon lights. What a depressing expereince it must have been for the visitors.
