Austrian artist Valentin Ruhry has been around the block when it comes to exhibitions, and in 2011 the artist created a work titled "Hello World" due to its lack of an actual title for The Austrian Cultural Forum in New York. The installment uses a number of electrical switches that each act as its own light. The piece then transforms as its viewers interact with it. Is this a more sophisticated, adult version of Hasbro's Lite-Brite? Either way, we commend the idea and dig the interactive aspect.
