idea for Neo 2nd generation: Accelerometer

Do a google on Sensiva or check out my blog at

You could build some very cool application control in with a good accelerometer, flick your mobile to the left to delete the window you are in or to the right to send a call to voicemail etc.

I use the google question mark command on sensiva about 200 times a day and love it.

I think the idea is good! 

But why only one? 

With one 3-axis accelerometer, we detect a move in the space XYZ: We
move our arm.

If we use 3 3-axis accelerometer (one in each angle of a triangle), we
can detect more movements: We can detect if the neo turn over himself
(with no global XYZ move).

For exemple, we can detect too, movements as:
 1.  a rotation of the hand
 2.  waves with the hand (not like "hello", but more as "approximately")

Does anybody know more about price and precision of the accelerometers's
chips on the market now?
