Is a tsunami hitting Amsterdam?

Now you can be the first to know:
Your macbook has a built-in motion-sensor.
(with the motion sensor it can detect if you accidently drop it an quickly "park" the hard-disk)

With seismac you can nicely register all those earthquakes and see that tsunami coming before anyone else does.

You can download seismac from here. 

And the callibration utility here. 

Another fun one is the ams visualizer.
It's a simple app that shows you how "tilted" your macbook is.
