real rose colored glasses

Glasses that have a cordless video camera on the front that wirelessly transmits information about your surroundings to a computer you would wear on your back. The computer would be programmed to recognize paths, walls, and small or large moving objects and would be able to alter them to the amount you desire. Approaching human beings would be seen as large moving blobs by the camera and could be converted into cartoon pigs, weird aliens, or supermodels on the LCD screens inside your glasses, cars could be converted into sprinting dinosaurs or space ships, and the grimy street below you into a yellow brick road. Of course distances would not be altered for safety reasons, but everything else could be changed.
