'Robbed of sight, I have a vision to help the blind see'

A blind man who narrowly escaped death when he was gunned down in the Philippines has developed software he hopes will offer life-changing independence to blind people. Marx Melencio was buying fried rice with his wife at a roadside store in Manila when he was shot in the chest and the head in an apparently random attack. The first bullet hit him 3mm from his heart. The second missed his brain by 2mm but singed his optic nerve, rendering him blind. Witnesses say the man who fired the gun was under the influence of both alcohol and drugs, but he's never been convicted.
