Glass

Glass blur is a simple and lightweight application that produces a blur effect. This effect is similar to the long-lost legacy Aero effect from Windows 7. This app uses a control from the Codrut Visual Library, more specifically the CGlassBlur control. This control takes a screenshot of the "Program Manager", aka. the Desktop, and then after bluring It, the picture gets cached in a Bitmap to be loaded fast with excelent performance.

The app even works with multiple displays.
