OK, I am not exactly sure where to put this thread. It is not quite CAD, and doesn't seem to fit anywhere else, so here goes...

I did a search and couldn't find any references to Geogebra on CD. It is really hard to describe Geogebra in a sentence. It is part Mathematica, part graphing calculator and not really the same as either of those.

If you click here it will take you to a model I threw together in a couple of minutes to look at the geometry of a double articulate arm. (One of Geogebra's nicer features is the ability to export dynamic web pages of it's models. Many content management systems, such as a Moodle, also have Geogebra plug-ins.) There are sliders to adjust the angles and lengths of the parts of the arm. This is just one example of how to use Geogebra. It's a really cool program, with a large development community. In any event, since I haven't seen any references here, I thought I would throw this up for the ChiefDelphi community.
