GooglyMinotaur is an AIM bot (or 'custom buddy' as he is called) created by Radiohead. This bot can be found on AIM most of the time. The bot's main function is to promote and answer questions about Radiohead. However, it can also play hangman, tell you your horoscope, give you movie listings, and various other things. It is rather well programmed and it is often possible to have actual conversations with the bot, eliciting humorous responses ('do you like to give the radio head?' 'yes i do'). It is not as advanced as the bot found at the 'AI the movie' website, but it is more accessible.
If you have AIM, send it a message and see what happens. Try cussing at it, it will ask you to apologize, and won't do anything else until you do.
