Alert! The Macintosh version will not run on the latest versions of Apple software, which no longer supports 32 bit applications. I am currently working on an update that will add refinements and additional capabilities, including lessons that guide students in exploring the data behind plate tectonics. If you have a deadline, please notify me at firstname.lastname@example.org. I will create a version that has all of the features that I have implemented to date.
