Seismac is a little neat application that shows the sudden motion sensor data on the newer powerbooks and macbooks as seismograph.

This is what comes out of it while in a Alfa Pendular train at 220km/h.

Doing it again while at the older tracks, closer to Lisbon (where the train tops at 70 or 80 km/h) will show a much bumpier ride. But then, I will need to do it while departing from Lisbon, not arriving, as my Powerbooks battery is seriously lacking in stamina.
