Microsoft is trying very hard with their Vista release. They paid to sponsor the whole Demetri Martin: Person show on Comedy Central last week. That guy (Demetri Martin) is hilarious - and he got a little cuter when I realized how funny he was, too. Related to the show is an odd "Clearification" site.
And then there's the flash piece my company did. (It's part of a whole series, really.) It's a pretty cute little animation. I didn't do a thing to help make the Flash piece - but we a couple of very clever creative dudes at Widemile.
