Display off animation in Windows 7

Does anyone kno开发者_开发技巧w how to change the default "fading out" animation when you put the computer to sleep or make the displays power down via a command line?

I was looking for a CRT-style animation as used in Android gingerbread.

The operating system is Windows 7 x64 (pro edition).

^{Also - I do understand it's unsupported and probably requires some DLL hacking (like in case of changing login screen mechanics).}

Just wondering if anyone looked for it / tried it.

Why not fake it? Take a screenshot, do the animation full screen, and once the screen goes black initiate the sleep/power down. Fading out from an already black screen is pretty hard to see, and might look impressive enough, depending on your needs.
