Ever wanted to try your hand at skinning? SkinStudio 4 makes it easier than ever. SkinStudio 4 lets you create visual styles for a variety of programs (best known for creating visual styles for WindowBlinds).
Version 4 introduces a new skinning format called the Universal Skin Format (USF). Users/skinners can import skins into USF from, for instance, .msstyles, and export them to other formats such as WindowBlinds and Windows Media Player.
