SeisMac is a Mac OS X Cocoa application that makes your MacBook or MacBook Pro (or SMS-equipped PowerBook or iBook) into a seismograph. It access your laptop's Sudden Motion Sensor in order to display real-time, three-axis acceleration graphs.
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
What's New

Version 3.0 of SeisMac's claim to fame is data export. What more can you ask for?
Well, all right, there is one more thing. SeisMac now intelligently handles the computer being put to sleep. It no longer tries to catch up to the present, and shows an error message that the timebase has been broken.
Works...but resizing window causes the Z axis to disappear with no hope of getting it back without quitting/relaunching. Window Zoom causes this effect as well.
Another nice feature would be to allow adjustment of the speed of the trace or scale. Save feature would also be nice.
It would be nice to be able to perform FFT analysis on the data. That would actually make it fairly useful for, say, figuring out the nature of weird vibrations when driving in your car.
(Yes it sounds odd, but I actually tracked down a bent rear axle by FFTing some accelerometer data once.)

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 for each axis. SeisMac is also compatible with older Sudden Motion Sensor-equipped iBooks and PowerBooks.

Otherwise, neat to show off to friends....
