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)

If you ever wanted to wear houses on your finger, now’s your chance (though it’s hard to imagine that any sane person would have such a desire)! Clive Roddy offers you an opportunity to fulfill your dream of having a ring that features houses, waves, mountains, or trees. In order to create these rings, first the metal is cut using a laser, and then the whole thing is hand painted using colored enamel. Though these rings are very pretty, it is hard to imagine someone wearing such a ring on everyday basis. These types of rings should probably be reserved for special occasions or festivals, rather than for everyday use. (Photo by Clive Roddy)
