Windows DreamScene is a utility that allows videos of the .wmv and .mpg format and other optimized animations to be used as desktop wallpapers.

[1] Prior to its official announcement, DreamScene was rumored to be in creation under the names Motion Desktop and Borealis.

[7] Additionally, in partnership with Dell, Microsoft released a separate DreamScene alongside its Product Red version of the Ultimate edition of Windows Vista.

[8] One of the purported advantages of DreamScene over previous methods of desktop animation is that it makes use of the GPU for display instead of the CPU, leaving the latter free to perform user tasks.

The software features its own Rendering engine which enables 2D video, 3D models, and even Interactive elements that respond to mouse cursor movement or keystrokes.
