Penguicon is a convention in southeastern Michigan designed originally to mix the communities of the science fiction fandom and Linux user groups. In addition to educational panels on science fiction in the media, attendees participate in professional and beginner-level panels on Linux and open-source software. Penguicon takes its name both from a Monty Python sketch and from Tux, the penguin mascot of Linux.
