Ode to Skulpture
I tend to believe that the best interfaces have already been made. Behaviourally, CDE is the best and most consistent interface ever made. It looked like ass, but it always did exactly as you told it to, and it never did anything unexpected. When it comes to looks, however, the gold standard comes from an entirely different corner - Apple's Platinum and QNX' PhotonUI. Between all the transparency, flat-because-it's-hip, and stitched leather violence of the past few years, one specific KDE theme stood alone in bringing the best of '90s UI design into the 21st century, and updating it to give everything else a run for its money. This is an ode to Christoph Feck's Skulpture.
