On a bright day, Nocturne

I travel a lot, and often find myself using my Mac and Verizon EVDO card in cabs or shuttles to/from airports to get a feel for the area I'll be at. During bright days, the screen can be hard to read. BlackTree to the rescue: Nocturne.

Nocturne provides a much improved version of the "White on Black" display in the Universal Access preferences pane. It works much better though - I've been told by a friend who's been having vision problems that it works much better for high contrast display.

I'd post a screenshot, but I can't figure how to take one that shows the inverted colors. ;) Try it.
