Try this for a cool Twitter tool – PepsiCo's new microsite, Pepsico Zeitgeist. The website monitors all the SXSW chatter occurring on Twitter, breaking the conversations down into color-coded categories: Arriving, drinking, registering, eating, connecting, and partying.
The coolest part is that that tweets scroll by in real time, letting you know who's waiting in the badge line and who's getting ready to enter "Drunksville" (actual tweet). There's even the "swarm" feature that shows where the tweets are emanating from on a map of Austin.
