200,000,000 Years of Continental drift around Antarctica
For a fascinating and detailed Powerpoint Presentation of one research group's reconstruction of the changes in continental configuation around Antarctica over the last 200MA, go to http://www.ig.utexas.edu/research/pr...PSESSID=def1b9
and click "Antarctica: Keystone of Gondwana." Starting at 200MA, each Powerpoint slide progresses 1,000,000 years, depicting tectonic changes in continental configuration surrounding Antarctica occurring over that time period, and progressing to the present. Definitely worth the viewing!

Antarctica's movement seems to have stabilized somewhat in the last 30 million years.
