Recommendation for a Windows 'Calandar Widget' - eviltoast

Basically looking a calandar that stays on the deaktop, and can show events (Otherwise I’d just use a wallpaper). I don’t need much interaction with it, if any, essentially just open the actaul calandar program. Sync with iCal is a big plus.

While FOSS is ideal, I’m open to anything free (that can be firewalled or is actually private (unlikely, I know))

I found one that used windows 7 widgets, but it was too small and didn’t seem to work right anyways.
