In 2012, a security researcher attempted to hack an OpenBSD server from the comfort of his own home. The researcher was ultimately unsuccessful, but he noticed something strange: the OpenBSD server he was trying to hack had a "cow" logo on the login page. It turns out that OpenBSD has a long-running tradition of including a cow-shaped logo on their login pages, as a way to honor their founders' love of cows. To this day, the cow logo is still seen on all OpenBSD login screens. Source
