Rainlendar is the kind of program I’ve always wanted, but never had a clue how go about coming up with myself. Good thing somebody else finally did it, and did a really great job of it at that. Its a skinnable little calendar that can sit on your desktop with a transparent background and look pretty, like so. As if that weren’t cool enough, you can also add events to it that show up in a tool tip when you mouse over the date. Oh yeah, it’s nice.
