Penguicon is a convention in the midwestern United States designed originally to mix the communities of 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 expanded its focus over the years to include panels and events for foodies, cosplay, filk music (the folk music of science fiction fandom), gaming, and makerspaces. Penguicon is a place where "hackers, makers, foodies, open source software junkies, anime buffs, and science fiction fans of all ages and backgrounds come together in a hotel for a weekend and totally blow the roof off."
Along with the panels, the convention hosts a "geek prom", a film room, swordfighting demonstrations, a cosplay contest, OpenCola (open source soda making), live action role-playing game, computer, board and cards.
Working alongside local makerspaces i3Detroit and All Hands Active, Penguicon has offered instruction in learning to solder electronic components, which allowed attendees to create their own LED badges.
Over a thousand participants have attended past conventions, which have featured Guests of Honor from Neil Gaiman and John Scalzi to Jon "maddog" Hall and Eric S. Raymond.
