Suso33 spent the last few days perched on a yellow crane to work on this impressive new piece on the streets of Madrid, Spain. Using a rather simple technique, the Spanish artist painted a brilliant piece which enters directly amongst our favourite artworks this year. This mural is a concentration of slightly outlined figures which are persecuted by their shadows, but if the viewer, instead of focusing on details, looks at the entire picture, what he sees is another figure. Take a look at more images after the jump and if you are in the area, you'll be able to find the piece at plaza del Poeta Leopoldo de Luis.
