This is a course for high school--Flash Animation and is offered through the K12 ICademy.
This has been a good choice. He has learned to draw all the animation in this mid-term assignment. It's a great way to add an elective to your home school schedule.
The tutorial in the class is easy to follow and feedback from the teacher helpful.
We did have to buy Adobe Flash CS5, but we got a student discount which was big. You can get it through the Homeschool Buyers Co-op website which has a link to the Academic Superstore. We got started by downloading a free trial for 30 days at the Adobe website. Simple to get started.
I figured out how to embed this Flash video he created, except for the interactive part.
