Language: POV-Ray Author: Ben Olmstead . Notes: POV-Ray is actually a raytracing program; however, the input file format is a Turing-complete language. To get this one to work, you have to use a command-line switch or configuration setting (depends on your OS) to send the 'debug' stream to a file. It'll also render as an incidental a completely black image. As usual, remove line breaks for perfection. #declare e="#declare e=#debug concat(substr(e,1,11),chr(34),e,chr(34),substr(e,12,71))box{x y}" #debug concat(substr(e,1,11),chr(34),e,chr(34),substr(e,12,71))box{x y}
