    Smartphone level horizon
    From: David Cortes
    Date: 2011 Jul 10, 16:21 -0700

    This from an inland navigator: I've broken my head trying to devise a way
    to get the equivalent of a pool of mercury for inland use of an artificial
    horizon. I've even tried putting a mirror on levers. Not satisfactory.
    Now, with a 20 search on my new Android, I've found a bubble leveler that
    seems to be pretty accurate. I haven't used it for taking star sightings,
    but it seems that if you orient the 4 in. screen with its long axis pointing
    toward the star and level the screen to 0, you could take a star sighting
    right off the dark, glass face of the Android.
