I've released version 1.1 of SeisMac, my freeware program that runs on Sudden Motion Sensor-equipped Macintosh laptops and displays three-axis real-time seismograms.
This version features a number of improvements:
* Reversed the horizontal scale (so the graph now matches a real seismogram) * Now shows vertical ticks every 0.2g * Now shows horizontal ticks every 1 second * Fixed a bug where one graph disappeared (often when resizing window) * Fixed a bug where the graph glitched from 0g when started * Much better performance; can now expand to full-screen without losing time * Can read saved calibration (stay tuned!)
