I see from my error log that somebody tried to access the above link, which is broken. Sorry 'bout that...here's a working link. I submitted this to Apple a week or two ago and it's in the top 50 widgets.
It's a slightly updated version which has shadows, if you have at least a semi-decent graphics card (that isn't an X3100 like in Macbooks, since the drivers are currently too buggy, though it works fine without shadows).
