I think we need to clear up one thing: What exact butterfly species of Morpho genus is used as MorphOS logo? The one Papiosaur used for his sticker seems to have slightly different wing proportions than the one in the MorphOS "About" menu.

MDW says it's Morpho anaxibia (as seen here), but I guess it could be as well/more probably Morpho rhetenor (here).

Does anybody know that?
