An interactive web interface for the webcomic xkcd resembling a Unix terminal. Comics can be browsed and displayed efficiently via the commands "first", "prev", "next", and "last".
Originally created as a joke for April Fools' 2010, the interface is now available at http://xkcd.com/unixkcd/.
Use the source, Luke.
Jokes are by Randall Munroe, Davean Scies, Chromakode, and various contributors from IRC.
