Twiddla is an online team whiteboarding (is that a real word?) tool that contains some powerful features including live text and audio chat. Here is a demo of how it works. Maybe we should have a go at conducting a meeting with the whole Creative Tallis team online at some point? I can think of lots of uses for this kind of service, especially the possibility of collaborating with students in other countries or working with experts beyond the classroom. It's free and doesn't even require usesr to create an account to join a meeting.
What do you think?
