The hacker theory is interesting, but I wonder if someone with access to this statue during off-hours performed this with a proper laser scanner and the kinect story is cover to make sure he doesn't get caught. Sounds like someone might be in trouble now. Of all the countries to have an intellectual freedom debate/trial, it seems that politically unstable Egypt would be one of the worst for any positive outcome here.
Its all a shame. We should have good 3D scans of every museum item of note by now and available for free for the public. How can we sell this concept to the boards, trustees, curators, and bureaucrats who control these items? Wasn't there a big controversy when high-quality color film came out way back when about publishing photos of art pieces and museum pieces? Seems like we're destined to re-invent this conflict over and over as technology advances.
edit: This bust is permanently housed in Germany, I just assumed it was on temporary loan. Thanks for the correction below.
