I'm good enough of a carpenter to know that a level or plumb bob of less
than 3 feet in length is basically useless, and for critical situations, one
needs one or the other of at least 5 feet.

So, this is mostly a "duck."

Thanks John!


It's more than a tilt sensor. It is an accelerometer that knows the 
exact orientation of the phone in 3D space - this is similar to the 
Wii Controller system.

I just got a great application called iHandy Carpenter. It turns the 
phone into a carpenters assistant (see attached photo):

A plumb bob
A surface level
A Bubble level that can be used to measure the angle of an inclined surface
A Protractor
And a scale

A great example of the kind of applications that are being developed 
for the iPhone. The accelerometer is also a major reason that the 
iPhone and iPod Touch are becomming the hot new mobile game platform.
