If you haven’t seen this already, it’s a pretty cool little app that NBC launched as part of their Winter Olympic coverage for the 2010 Vancouver Games. The Tweet Tracker is made up of a picture grid that expands and contracts each sport depending on the current buzz being generated.

You’ll also be able to dig in to see who is tweeting and the links being tweeted from. I think the apps design could have been a little better, but overall a great app to play with on NBC.

Help us share the digital goodness!
