They say a messy desk is a sign of productivity... and in the computer world, your desktop is your messy virtual equivalent. If, like me, you use your desktop to frequently store "temporary" (as in 6 months+!) files, text notes, images, etc. then you may appreciate the release of BumpTop for Mac.
BumpTop is a 3D desktop utility which replaces your existing OS desktop in favour of a slick 3D virtual room where you can treat files on your desktop as you would in a normal desktop environment. You can collate related files together and pile them in a stack, you can pin files or pictures against your virtual walls, you can even toss files across your desktop with satisfyingly realistic physics. Now out of Beta, and having previously been released for Windows almost a year ago, BumpTop finally makes its debut on Mac OS X.
The standard version of BumpTop is totally free, but there is a 'Pro' version available for keen desktop clutter enthusiasts for a nominal $29 which provides additional cool features such as Find-As-You-Type, multitouch gestures for Macbook owners with multitouch trackpads, ability to 'flip' through files using your mouse scroll wheel or trackpad, and no limit on the number of sticky notes you can have in your virtual desktop.
