Personally, I'm fascinated by how stuff keeps sloughing off Gondwana and 
wandering northward across the Tethys/Indian Ocean to crash into Asia, 
culminating with India (and eventually to include Australia?).  Is there some 
overarching explanation for this northward drift?

Also, what's the status of Rodinia (by which I mean the hypothesis that 
Australia and Antarctica were once joined to the west coast of North America)?
