I've been watching this series, and they recently had an episode about Machu Picchu. (Someplace I would like to visit.) I was amazed at how large it really is, and how it was built. The engineering involved, and thinking ahead.
LOVE the series.......extremely interesting from a CG point of view.....to be able to have x-ray
vision and "see" the unseen.....missed Machu Pachu, so I am eager to catch up....
