Aha, well - researched a little, and that stuff is damn hard to find. Well - will keep an eye out for it!
Well, after some more researching I came by two other programs that are extremely similar to your description:
First one if called Compiz.
It's a program that can design your monitor and desktop in a extreme loads of ways. And also make the bright light reduced to spare your eyes.
Compiz download - Compiz 0.8.2 / 0.7.8 (Can be downloaded here)
And Xflux - An extremely effective program that lets you control the light on the monitor and desktop to also save your eyes.
xflux - Rapidshare files download (Can be downloaded here)
Hopefully that's the ones, or similar to them :>
