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.

Greek actress Katerina Lehou, playing the role of High Priestess, lights a torch during the dress rehearsal for the Olympic flame lighting ceremony for the Rio 2016 Olympic Games at the site of ancient Olympia in Greece, April 20, 2016. Fire spurted from the concave mirror as a priestess, kneeling in her long, pleated dress before a ruined Greek temple, focused the blazing sun's rays on her metal torch. Come rain or shine on Thursday's official lighting ceremony, Rio de Janeiro has now secured its Olympic flame, which will burn in the main Olympic stadium throughout the Aug. 5-21 games.
