These images of abandoned hospitals across Italy are not for the faint-hearted. Both of the hospitals featured in the photographs are Italian asylums – known as manicomios – that were used as mental hospitals. Shut down by law in 1978, the derelict buildings are visibly overgrown and make for very eerie portraits. Photographer Thomas Windisch, 32, of Graz, Austria, said the asylums, located in top-secret spots, can get very creepy when there aren't many people there with him. Here: a hallway within an abandoned hospital. (Photo by Thomas Windisch/Caters News)

Kim Joon is a Korean artist who specializes in creating images that resemble hollow porcelain human body parts painted in bold patterns from famous ceramic brands including Royal Copenhagen, Herend, and Villeroy & Boch. His latest project is called The Rocker and features a number of pictures of porcelain hands laying on a dish patterned in style of different famous rock bands of the past. The images are so vivid that it makes you think that these hands are actually real and not digitally crafted, though it would be amazing, if someone were to actually make a creation such as this in real life.
