I'm not convinced we need full-3D graphics and physics simulations just to work a computer.
What we do need, IMHO, is more pervasive hardware acceleration at the OS level, and rich support for animations. Windows fails horribly at this, but they're making promising strides - motion is one of those important UI bits that has basically been ignored up until now.
It would be great if BumpTop can navigate the full drive and directory tree using the cool features of BumpTop without resorting to Explorer and without being tied to the desktop.
We have an experimental "Bump This Folder" shell extension, which provides a little button in Windows Explorer that turns the current view into a BumpTop. It needs to be enabled in the BumpTop settings.
