Rainlendar is a slick-looking lightweight calendar and todo list which runs on your Windows desktop.
With transparency and event-specific icons, Rainlendar is a visual delight that that doesn't hog up screen real estate. Rainlendar supports event alarms and syncs with your Outlook calendar. The to-do list is particularly useful: make a list of "things to accomplish in this computer sitting" and cross 'em off one by one. (Soooo satisfying, that finished-item crossing off.)
Encourages focus for - wait, what was I saying? oh, right - short attention spans.
