10/10 IMHOTEP

[FrozenInferno]

Looks pretty nifty. Checking it out now.

Edit:
After installing it on my desktop, my laptop, I noticed my eye strain disappeared when it transitioned to the warmer color. My girlfriend set her laptop right next to mine and noticed the difference. I was showing her a youtube video and she noticed the extra "brightness" (actually just the perceived brightness) of her screen as soon as she looked back. She immediately asked what I did to make my screen warmer. She's afraid we're spoiled, and doesn't want to work on computers without it. I'm afraid she's right.

tldr; 10/10, most definitely.

I don't think you have a girlfriend. Enjoy your laptops.

Been using it for a few days now, and yeah, eye strain is much less. Not totally gone though. It sort of bothers me that whites are now khaki, but I don't notice it that much while I'm actually doing something.

After using this for nearly 2 weeks now, I have noticed:

-Eyestrain is a lot less.
-Less tired during early hours of the morning.
-Better sleep.

Fantastic little program.
