If you were on drugs and driving (not that we'd advise that!) then your vision of the road is likely to be something like one of Erik Johansson's composite photographs. Johansson, a photographer and editor, is an expert when it comes to creating images that trick the mind. His optical illusions are unsettling and definitely make you look twice. Make that three times. At least. Check out the collection of his works below for some mind bending art appreciation. And also the photographs featuring roads? They were in fact commissioned for a campaign in Australia highlighting the dangers of driving whilst on drugs!
