"Kopernik" is the Polish name of the Polish astronomer Copernicus, aka 'the father of modern astronomy'.
In a way, this skin was an attempt to achieve a style similar to that of a skinner from yesteryear whom I admire: Marek Wojtal, another Polish skinner. Although, my skin is not as organic or technically impressive as Wojtal's skins - but it is more user-friendly :)
I hope you enjoy it :)
Also skinned is the AMAROK plugin.
Good skin with a number of good animations. Well worth the download, and with its ease of use it could very well be a keeper.
