It’s been going around the blogworld, but if you haven’t seen it already, do check out BumpTop 3D Desktop Prototype. Rather than a useful place to store files (I can’t organise a real desktop of any kind) I would like to use something like this as a launcher/widgetboard, something like the Dock + Dashboard. Maybe desktop too, if I can see filenames more easily. Regardless, big thumbs up to the UI innovations shown here.
