Awesome! I love playing with time and seeing the motion of the plates. I just used GPlates to show friends how Baja California was ripped northward, how the alps were created, and how India really beat it northward, only to collide with the rest of Asia and create that 40-car pileup we call the Himalayas. Pretty cool for geology enthusiasts. I'll have to lean how to do more with it than just load in the sample data sets.

Some may say the data is incomplete (ie Cuba crosses through Mexico ~67 million years ago) but having studied geology, the actual data is pretty spotty and its fantastic that geologists have been able to reconstruct what they have. I know how hard it is to figure stuff out in the field, having done some of it - and that data represented here is a testament to the detective-work done by those studying plate tectonics.
