Twiddla is a web-based meeting playground white board. Mark up websites, graphics, and photos, or start brainstorming on a blank canvas. Browse the web with your students or make that conference call more productive than ever. No plug-ins, downloads, or firewall voodoo - it's all there, ready to go when you are. Browser-agnostic, user-friendly. And it's FREE!
How is it different from other collaboration tools? (e.g., WebEx)
First of all it's free.
Second it's available to anyone, anytime.
Third, there are no plug ins - all you need is your web browser.
Fourth, you can interact with the web (or any uploaded picture, PDF document or widget) AND mark it up at the same time.
