The Cowon J3 is far from being abandoned by the user interface modding community (and the S9 and X7 benefit from being compatible). Well known Korean UCI designer Asurada presents a teaser video of his newest creation, ASUCI v2.
Using 45 degree tilted interface elements would usually be just a gimmick, but Asurada obviously put a lot of thought into the design and usability of his theme. Next to ergonomic left-handed usage I especially like the increased length of the slider bar, allowing for more precise scrolling in a track. It seems to hit a quite sweet middle ground between a portrait- and a landscape-oriented interface.
