Geeked out Penguins rock most wearing the beanie hat propellerhead thing. Looking for something that says Linux? Not defined by a word, but rather defined by image the Penguin sticker says geek. Penguins and Linux have been linked since the beganing of time :) Normal Penguins don't wear beanies but geek loving powerusers like yourself know that the smart ones do.
Got that new laptop running Linux, or that car with the bare windows that are screaming to say geek? The Penguin sticker comes in both white and black. White for the tinted car windows and darker computer case colors and black for the whiter computers and anything else white screaming for the Penguin like the refridgerator.
