I'd like to mention an application I've written for recent Macintosh laptops (which have internal three-axis accelerometers). SeisMaCalibrate calibrates your laptop's Sudden Motion Sensor so that my previous application, SeisMac, can create accurate three-axis seismograms. It's free for Mac OS X 10.4.
You'll find SeisMaCalibrate at <http://www.suitable.com/tools/seismacalibrate.html>. You'll need to update to my most recent version of SeisMac, available at <http://www.suitable.com/tools/seismac.html>.
I'd appreciate any and all feedback on either SeisMaCalibrate or SeisMac.
Thanks, Dan Griscom Suitable Systems griscom@suitable.com http://www.suitable.com
