What your finished product will look like
So what's this wacky phylm thing suposed to look like anyway? Essentailly this is your chance to draw on top of video. What you can do is really only limited by your imagination and the time you have to work on the project. In principle anything you can draw with Flash can go on top of that video. This includes everything from simple text to complicated animations.
If you saw student examples of projects at my presentation on August 6th at the AAPT National Meeting, consider yourself lucky. Unfortunately, for legal reasons I can not share my student projects over the internet. However, I will soon place a mockup piece here to help give you an idea of what can be done.
