Product Description:

SeisMac turns your Sudden Motion Sensor-equipped laptop into a three-axis seismograph. It shows a scrolling chart of the three axes of acceleration, reading two hundred samples per second.

The resizable, real-time scrolling display shows an enormous amount of acceleration information. Place your laptop on a table, and see the seismic waves from tapping your toe on the floor. Lay your laptop on your chest and see your heartbeat. And, of course, if there is a real earthquake, SeisMac will be displaying full seismic information while you drop, cover and hold-on.

When running on the MacBook or MacBook Pro, SeisMac has a range of plus or minus two gravities of acceleration, displaying 256 values per gravity, sampled two hundred times per second. SeisMac is also compatible with older Sudden Motion Sensor-equipped iBooks and PowerBooks.

SeisMac is free for Mac OS X 10.4 or later. It is compatible with MacBooks and MacBook Pros, as well as Sudden Motion Sensor-equipped PowerBooks and iBooks.

very nice this update... now it would be nice to be able to export the raw sensor data... or some way to use it to do stuff with it....

Incredible! - Version: 1.3, 2/9/2007 04:56AM PST

...but I would really like it to be a bit more flexible. Variable sampling rate, for example..

Very neat! - Version: 1.3, 12/16/2006 10:07PM PST

Would like two features:
1. ability to sample/display less frequently (cpu intensively)
2. a Dock icon, like Activity Monitor has; or menu item

Other than that, it's perfect for the price.
