iPhone Accelerometer Demos? [Updated]

Gizmodo reports on one blog who claims to have been able to access the iPhone accelerometers to produce some interesting effects.

No one can yet attest to the accuracy of these demos, as they do seem a bit more sensitive than the accelerometers appear to be on the iPhone.

Update: Source code posted. As people have pointed out, Apple's use of the accelerometers for screen position would, of course, have a higher threshold to prevent unintentional rotation.
