A few weeks ago I mentioned Sage and Beamer, well beamer has been going pretty well, I am using it several times a week in various classes. I thought I was going to try Sage, but haven’t gotten to it yet, although I have come across a free software (not open source) package called GeoGebra.

It is given as Dynamic mathematics for schools. It is has much of what I thought I might want in Sage and is easier to handle in some ways. It is a Java package that can create java jars that can be easily placed into html pages that can be used to demonstrate graphical concepts in Algebra and Geometry. It understands Latex input for labeling, it can export postscript that can be used in a Latex document (ie Beamers). I think I am going to like this.
