This is amazing public 10-story art installation by Korean artist Choi Jeong-Hwa, the installation made up of 1,000 recycled doors in South Korea around 2009. These bright colored doors transformed this originally bland building into an visual master piece. Since he is unable to draw or paint, Choi spends much of his time walking around the city seeking interesting trash and discarded objects and expressing them through photography, using ordinary objects in extraordinary ways.
