This is the tower of the main mosque of Ushaiger.  Ushaiger is one
    of the oldest towns in the Saudi region of Najd and it was a major
    stopping point for pilgrims coming from Kuwait, Iraq and Iran to
    perform Hajj or Umrah. It was mostly abandoned 50 years ago, but
    is now being reconstructed and people have started to move back
    in. Also see http://thompsonsinsaudi.blogspot.com/2011/04

    25°20′33″N 45°11′0″E. ... 200 kms each way of easy
    highway from Riyadh. As part of a training exercise for a group of
    scientists and engineers from KACST in Riyadh, Tom DeFanti and
    Andrew Prudomme went with the group to shoot these CAVEcams and
    also attempt some structure from motion (SfM) image capture.
    Thanks to Saleh Al-Harti, Mohammed Alfarhan, Azzam Asuhaibani, and
    Badr Altasan of KACST who got us to this amazing museum, and
    helped us photograph this reconstructed town.
