I have bought licenses for iStopMotion for Edith and Leo laptops. Please contact me at ludwig@siu.edu if you plan to work on either laptop this week and I can send you the information to register the license. I changed the permissions on the two laptops so that you, the student, can download software if needed.
Decent overview (if a little geeky):
