Hot and Cold

If you're feeling frisky, or want to liven things up a bit, you could play the “Hot & Cold” game while watching people run around the venue. If someone is getting close to your hiding spot and you know who it is, you could call out on Twitter that they’re getting warmer…. If you don't know the usernames of the folks playing along, you could use a description of the person or their clothing, instead of a username.

“Someone in seafoam pants and a hot pink flamingo shirt is getting awfully warm right now....! #sxsw #sxswtreasurehunt”

This is a quick way to enliven the atmosphere as people run about.
