Gragraph, the home seismograph

Gragraph does not rock your world, but it at least beeps when something else will.

It is $150 and does not have English instructions.

   Can I trade mine for a home Spirograph?

   I think I’ll get more use from the latter.

2. [Rob Beschizza]

   You will!

   Oh, how I loved my spirograph.

   Or you could use SeisMac or any other program that works with your Mac’s built in accelerometers.

   Or buy a $12 2-axis accelerometer, like the Memsic 2125, and hook it up to your Arduino.
