I just noticed on my tab for this site Tux looks a little rounder than usually. I haven't noticed it before.
It this because my screen resolution isn't right? But everything else looks normal. The other tuxes on the site look like their slim old selves, it is only the one on the tab and by the URL.

The only other thing I could think of is that right now I am saddly not on a linux box, so does the icon show up different in firefox on windows than in a gnu/linux system (I don't know why that would be though)?

Maybe he is fattening up for winter?

I'm in Firefox, and he looks fine to me... is your monitor's pincushion screwed?

That's favicon. It's probably stretching the image because it isn't exactly square.

Tux is cuter when he's fatter.

Somebody else said the exact same thing about the fatter tux in the SuperTux favicon. Must be the Herring Effect.
