Since Sundays are slow, it seems there's nothing better to pass the time than an OpenGL technology demo from NVIDIA. It makes extensive use of NVIDIA own GL extensions, so it probably won't work on RADEON 8500 cards. After you download the demo from the above link, you will also need to get this glut32.dll file. Put the .dll file either in your Windows\System directory in the same directory as superflow.exe.
Then all you have to do is sit back and watch the pretty effects. The effect is neat, but I wonder how much use it will be to developers.
