Perhaps a game? Perhaps of minimizing inter-city walking/swimming/flying physical travel, for time travelers whose position when time traveling is anchored to the plate? So "Start at city A. ... Now, fly to Mumbai, and ride it time-forward across the Tethys Sea to Asia. Then fly to D, time-backwards to Gondwana, and fly to E (goal). Distance flown: N km. Distance drifted: N km. Time traveled: N Ma." Note that the existing app can simultaneously show more than one city. I missed that at first.
