Penguin the Linux Mascot : Story goes like this..

Linus Torvalds, the creator of the Linux Kernel, was visiting his friend Andrew Tridgell, the creator of the Samba suite. They were walking through the Zoo in Canberra when, without warning, a huge flock of vampire attack penguins dove out of the sky and tried to carry Linus away. Fortunately, Andrew had an umbrella. Still, one of the birds was able to nip Linus' hand with its fanged beak. Rumor has it that on moonlit nights Linus still runs out into the darkness and jumps, stark naked, into icy water. Of course, he's Finnish and may always have done this. In any case, this is why the Penguin is the Linux Mascot.

Why Penguins?

This email from Linus in response to this very question seems to explain the significance of the Penguin:

Umm.. You don't have any gap to fill in.

"Linus likes penguins". That's it. There was even a headline on it in some Linux Journal some time ago (I was bitten by a Killer Penguin in Australia - I'm not kidding). Penguins are fun.
As to why use a penguin as a logo? No good reason, really. But a logo doesn't really ave to _mean_ anything - it's the association that counts. And I can think of many worse things than have linux being associated with penguins.

Having a penguin as a logo also gives more freedom to people wanting to use linux-related material: instead of being firmly fixed with a specific logo (the triangle, or just "Linux 2.0" or some other abstract thing), using something like a penguin gives people the chance to make modifications that are still recognizable.

So you can have a real live penguin on a CD cover, for example, and people will get the association. Or you can have a penguin that does something specific (a Penguin writing on wordperfect for the WP Linux CD, whatever - you get the idea).

Compare that to a more abstract logo (like the windows logo - it's not a bad logo in itself). You can't really do anything with a logo like that. It just "is".

Anyway, go to "http://www.isc.tamu.edu/~lewing/linux/ for some nice examples..
