Nocturne: "night vision mode" for your Mac
When Nicholas Jitkoff (of Quicksilver fame) pops up on twitter and announces a new app, it's probably worth a look. In this case it's called Nocturne and is a simple program to put your Mac in "night vision mode." The main thing it does is invert the colors on your screen (which you can accomplish natively just by hitting cmd-opt-cntl-8), but it also has options for making the display monochrome and tinting it (the default is a kind of sepia) as well as suppressing your Desktop picture and window shadows. I think the idea is simply that white on black is easier to read at night.
Nocturne is a free download from Blacktree.
