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)

As you look at the set of pictures created by Tom Kondrat during his travels in Iceland, the first thing that comes to mind is the word “loneliness.” These pictures lead you to believe that Iceland is a desolate expanse of icy wasteland. You can almost imagine the strong wind howling in your ears, as it chills you straight to the bone. And as you’re walking down so beaten path, you’re all alone, with not a human soul for miles in any direction. This may prove unbearable for some, yet others find comfort in such places. With no one there to bother them and distract them from their thoughts, they can finally be at peace. (Photo by Tom Kondrat)

Fifty years ago, as France exploded in mass protests, words scrawled on the walls of the Sorbonne summed up the revolutionary zeal of the time: “Run free, comrade, we’ve left the old world behind!”. Sexual liberation, artistic creativity and anti-capitalism were the order of the day. For those who were there, it was an unforgettable time.
