I love office (as a shareholder) and I live in Word, though I'll keep my thoughts about the ribbon to myself. All of that aside, the Australia Office folks used Silverlight to create a fund raising site on the premise of "sit through a short commercial and we'll give money to education." Since its Silverlight and Education and Microsoft (three causes I care about) I thought I'd pass it along.
Click here or on the image (that's the picture on the left!) to watch a (truly cheesy video of an Aussie kid telling you how cool Office is, which you must watch all the way through, but it is short) and Microsoft donates 1 Aussie dollar to education (don't ask me how much that is). It takes 30 seconds, and the site itself is nifty (at least in concept).
(I like the waving hands; I don't like the fact that the videos take about a year and a half to load, but Australia is very far away.)
