Wifitti looks like an interesting tool for the classroom, but also for presenations and conferences.
You can add up to 5 tags to be pulled in to your Wifitti wall from Twitter and Flickr. Contributors can text messages to the wall or enter them on the web.
Wiffiti publishes real time messages to screens in thousands of locations from jumbotrons to jukeboxes, bars to bowling alleys and cafes to colleges.
You will receive a URL for the wall or can also embed it on your website with html code. The Wifitti I created below has the “@langwitches”, “langwitches”, Around the World with 80 Schools” and “Silvia Tolisano” tag.
