I have created the flash movie as shown above. But I did not create video format suitable for Youtube.
You are welcomed to do so. I know that you have post several youtube movies.
So it will be easier for you to do it. (I have never post any youtube movie, and I will need to learn how to do it.)
It will be even better if you could also create youtube movie for the simulations available in this web site.
It will be easier for me to create simulations with EJS and it will be better for you to create youtube movies.
So that we all can do what we can do best. Both of us can make contributions to the web community.
I think this will be the best combination for us to collaborate with each other.
What do you think!  :)
