I have been playing around with GoAnimate which is a website that lets you build Flash animation clips. Besides making it very simple to create (if you can build a PowerPoint, you can build GoAnimate) - they have licensed characters from third-parties such as Star Trek. You can also upload your own.
I thought it would be fun to see if this might be another way to explain technology information.
You can check out my clip that I built to explain virtual directory (in general, not OVD specific) technology using the characters from Star Trek.
