The API does not provide a mechanism but it can be done:

    www.polyarc.us/uglyhack

If it is your overlay, it can be done with "onload" / "onerror" event
handlers:

    www.polyarc.us/frameanimation.js

The file:

    www.polyarc.us/ridge

demonstrates it in action.

"Frame Animation" is feasible.  "Flight Simulation" is difficult
without the ability to disable smooth panning.  Without an
interruptable, priority based tile "pipeline", performance will be
lousy.
