Whitespace

Whitespace, designed in 2003 by Edwin Brady and Chris Morris, is an esoteric programming language that uses only whitespace as syntax. Everything other than spaces, tabs, or linefeeds is ignored. Whitespace got a brief moment of fame when it was posted on Slashdot on April 1st, 2003. Most people took it as an April Fool's joke, which it wasn't.
