BumpTop was a skeuomorphic desktop environment app that simulates the normal behavior and physical properties of a real-world desk and enhances it with automatic tools to organize its contents. It is aimed at stylus interaction, making it more suitable for tablet computers and handheld PCs. It was created at the University of Toronto as Anand Agarawala's master's thesis. Anand Agarawala also gave a presentation at the TED conference about his idea. The 1.0 version was released on April 8, 2009, along with a fully featured pro version as a paid upgrade. On April 30, 2010 the author announced that BumpTop was being discontinued and that they were taking the software "in an exciting new direction." Two days later, it was announced that the company had been acquired by Google. On January 5, 2011, Google released a sneak preview video of Android 3.0 Honeycomb showing a 3D desktop with features purportedly taken from BumpTop.
