Also if you are really trying to emulate a real accelerometer
remember that they always record 1g _upwards_ due to gravity. You'll
need to add this to your calculated acceleration. If you want to be
really clever you could also fiddle with frequency response - some
accelerometers record down to 0 Hz, some don't and have a minimum
frequency. They all have a maximum frequency too.

Cheers
Bill
