Street art started out as unintelligible words written on concrete walls with spray paint by gang members or silly kids. Now, however, it evolved into a unique form of art that might stun and inspire awe in the onlookers. For example, the artist that goes by the name 1010 specializes in creating optical illusions. His creations look like portals into other dimensions, without any hint that it might simply be a flat concrete wall painted over with multicolored paints. These pieces of art are so good that it is hard not to reach out into these ‘holes’ to find out whether or not they are real. (Photo by 1010)

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.

Bouwe Brouwer: Postcards from Fryslân (series finalist). “People from Fryslân are looked upon by the rest of the Netherlands as stubborn people. Going back as far as the Spanish occupation, they have a history of resisting authority. Postcards from Fryslân is still an ongoing project – hopefully a lifelong one. When it started, it represented only a collection of places that seemed interesting. Currently, the hope is to cover most of the province, as you never know in advance where the best narratives are. But still, it is all candid, unposed and in the public realm”. (Photo by Bouwe Brouwer/Street Photographers Awards 2021)
