[Etoys] Upcoming talk

[Joe Apuzzo]

I will be giving a talk this coming Wednesday (www.mhvlug.org)
http://news.squeak.org/2008/05/24/new-yorkers-chance-to-see-squeak-based-education-tools/

I'm working up my slides and I will be using the latest squeakland/etoys
build to demo.
I've done the "car" demo ( mastered that) and also can demo the "car on
a track".
But does anyone have any suggestions for math and science? aka something
that
I can build on the fly and show a topic that a Middle School or High
School teacher
would do in class?

Thanks
