A 3D rotating clock screensaver. This screensaver has the capability to save power during rendering of frames. It is achieved by a special usage of GPU and CPU (GPU is used only during drawing of the next frame and CPU usage is very small as 3D transformations are very simple and they depend only on timer).
System requirements:
CPU at least Intel Pentium III or Compatible
RAM: 128Mb or more
Video: At least support OpenGL1.1 (DirectX 6.0) required
