Firefox has added some accelerometer / orientation JavaScript events in their
nightlies.  It would be nice to have this for WebKit as well.

separate things

Unfortunately, there's no "API" apparently for desktop macs, though accessing
accelerometer data is described in "Mac OS X Internals: A Systems Approach" by
Amit Singh (section 10.7.5).  Accelerometers are available for some PC laptops
as well, though the usage on a laptop seems a bit of a stretch.
