The Macintosh Business Unit (MacBU) at Microsoft has announced Art of Office, a user-generated community site where people can submit artistic and/or useful content using Office for Mac applications. It allows people to share, rate, remix and discuss user-submitted content with other Office for Mac users around the world, whether it’s creating pixel art using Excel (such as the famous “Happy 10th Birthday” art), developing an animated short story in PowerPoint or artistic pieces in Word.
