This week, I'm introducing a new occasional feature: Casual Friday. In it, I'll share uses for the Office applications that we've all put to such good use being productive at work to enrich our personal lives as well.

I recently found just such a use over at the Microsoft Excel blog, where they've released a template that lets soccer fans easily track the 2010 FIFA World Cup games using a simple yet innovative approach.

What's particularly interesting is how the template was made - without code, just conditional formatting, formulas, and a little-known Excel feature called the Camera Tool. For a detailed (and fascinating, for Excel fans) look at how this template was created, read the excellent walkthrough article by Diego Oppenheimer on the Excel team.

What are your favorite non-work uses for Office applications? Post a comment below or send me a tweet.
