I only just found, and installed, this but had to share it due to my ribbon affection. It’s a “game” that aims to improve your Office skills while you work. Read all about it on the Office Labs blog:
Hi! I’m Jennifer Michelstein, a Program Manager and casual games enthusiast in Office Labs. My current project is Ribbon Hero, which works on Vista and Windows 7, and in Excel, PowerPoint, and Word 2007 and 2010.
Ribbon Hero watches what features you do and don’t use, and then it recommends challenges for you to play, to hopefully expose you to new features. The first time you complete a challenge, you’ll earn points. But then we want you to use those same features in the app (on another day) to prove you’ve mastered those features! You can max out a feature by using it twice, on two separate days – and only one of those times can you get points from playing the challenge…
And it’s the last time I’ll mention this: Want your own “Love the ribbon”?
NOTE: As I don’t have rights to reproduce a real product ribbon the CafePress image has a brand less generic ribbon in the arrow portion.
