I've been brewing a tech demo game for my 2D game engine for more than a year, now.

One of the target was to use other FOSS' mascots -- like what Wormux (now WarMUX) did.  The famous of which is obviously, none other than, Tux.

I stylized Tux to fit the art style used in my engine's mascot.  With comments from my friend we ended up having two designs.

I'd like to ask which Tux to use in our game, Smack.

I plan to release the sprite once a final design is chosen -- this is so others can make use of it on their games as well. :)
