Epidermis 0.4 has been released, with a brand new feature: Xsplash themes. Epidermis is the first GUI program to offer this capability, as far as we know. Changing the look of your boot-up screen is now as simple as changing your wallpaper.
Pigment creators also have a new feature to play with: automatic preview generation. Now you don't need to the hard work of taking screenshots yourself any more, Epidermis Creator does it for you.
