BumpTop, the popular physics-based 3D desktop environment for Windows, has now been made available for Mac OS X 10.5 and later, offering users new features for organizing their desktops. BumpTop offers users multiple surfaces on which to store files, allowing users to alter the sizes of individual items and take advantage of several organizational features such as piles.
BumpTop for Mac is available in two versions: a free version offering most of the application's features, and a $29 pro version that adds multi-touch functionality, unlimited numbers of sticky notes, find-as-you-type filename searching, and the ability to easily flip through piles of documents.
