And I thought that was it, I'm very thankful and luckily I checked the the
forum, thank you very much, I'm a student in Mexico and now this will help
where the Internet connection is not available. Now I can use the applet ok, I
was only able to download a non working one from a link that appeared in a
error page.

I think this is a very good applet to see the projections and to teach kids.
Thanks.
