Black Light

Black Light is an interesting utility that inverts the gamma on your screen and thereby inverts the colors. This is supposedly a good way to extend your battery life and read in dim lighting, but we’ve never heard of such things. We supose having powering less pixels would be a good thing, if a screen’s black was actually a non-powered pixel. But they’re not, so the battery life extension is a farce. Otherwise, the whole readability thing is up to the user. In any case, take a try with this free MacOSX utility. It might not be something we’re interested in, but it might something that you are.
