A Korean television station has produced a 2-part documentary on 12th/13th century Angkor in 3D. The trailer has been making the rounds on the Cambodian news websites, it looks really fun!
There is also a brief “making of” clip on YouTube. Part of the story focuses on Jayavarman VII, who built Angkor Thom, the Bayon and many other buildings large and small. It reminds me a bit of the fiction book The King’s Last Song, which alternates between the story of a French archaeologist who finds one of Jayavarman’s ancient manuscripts and is subsequently kidnapped by a former Khmer Rouge soldier AND an imagined account of Jayavarman VII’s life. It was a great read.
Of course the ultimate Angkor in 3D experience is to visit it in person yourself!
