Skulpture is a GUI widget style for KDE 4 featuring a classical three dimensional look with shadows and smooth gradients. Included is a matching window decoration for KDE 4. If you are looking for a matching Plasma theme, I highly recommend Atelier.
Despite the lack of time to work on Skulpture, I managed to get a small release out the door. This version only fixes a few small bugs in the widget style; the window decoration is unchanged.
Regarding the future of Skulpture, I have many plans, but not much time. The few hours I could spent went directly into KDE bug fixing, as I plan to make the switch to KDE 4. But you can keep me motivated by reporting bugs or suggestions 🙂
A note to packagers: If you have build scripts that fetch the source from a web address, please do not use the kde-look.org address, but use http://skulpture.maxiom.de/releases/skulpture-$VERSION.tar.bz2; I keep an archive of released versions (currently 0.1.3 and 0.2.x) there. This avoids breaks of build scripts on version updates.
