Here's a great new tool that's totally free.Throw out the transparencies and the Expo pens.
You can have all your favorite graphic organizers at your fingertips. Copy your old favorites (Venn Diagrams) and have them anywhere, anytime.

Gliffy allows you to print and "save as" in several common formats.

Gliffy even has an embedded image search function, very cool, not to mention fast.
But one of the best features Gliffy has is the ability to have your diagrams shared on the web, imagine that in the computer lab, and people can work on their diagrams collaboratively, no scissors or glue.

Give it a try, it's way easier than those commercial diagrammers that cost a lot more and you don't even have to install it because it's web based.
I'll be looking for people to share examples.
