From The Download Squad (bookmark the site, it's always got some kind of cool download posted) comes a small widget calender: Rainlender, that looks pretty cool. It's not a konfabulator widget, but a widget of it's own :)

I like Life Hacker. I like Konfabulator. so what could be natural than the Life Hacker Widget :) Get your hack on! Also, check into konfabulator every once in a while. New widgets come out all the time and you may find one you can't live without!
