Desktop Panorama is an opensource panoramic virtual desktop that uses the innovative concept: the virtual desktop area is represented as an infinite bar and windows can be freely moved around it, in the same way as they can be moved around the normal desktop. Changing the view (the desktop) is done by selecting an area on the bar using a mouse.
This program is also useful when using it with a touchscreen and it responds like it was made for it, although it originally wasn't. It's tested on all Windows versions from Windows XP to Windows 8. I tried it on Windows 10 RC and it works well and it should support it in the next release.
