BumpTop is a 3D desktop environment that simulates the normal behavior and physical properties of a real-world desk and enhances it with automatic tools to organize its contents.

On January 5, 2011, Google released a sneak preview video of Android 3.0 Honeycomb[3] showing a 3D desktop with features purportedly taken from BumpTop.

Extensive use of physics effects like bumping and tossing is applied to documents when they interact, for a more realistic experience.

BumpTop currently supports Windows XP, Vista, and 7, and a version for Mac OS X was released into private beta on January 18, 2010.

While the download page on the official website does state: "Internet connection required for activation",[7] this may not appear in other sources such as Cnet.

“BumpTop creates a brand new user experience for computer desktops,” said Ted Chen, CEO of TUL Corporation.

[15] Shortly after its acquisition, Bumptop announced plans to remove the software completely from its website, only giving "End of Life" support to those who bought the Pro version.
