I saw this picture of a Dorje Shuden 3D mandala, said to be at the Chojin Lama museum in Mongolia.
This thangka is also at the Chojin Lama Museum.
Here's some info about the museum.
THE CHOIJIN LAMA MUSEUM(
http://www.legendtour.ru/eng/mongolia/ulaanbaatar/choijin-lama-museum.shtml)
The Choijin Lama Temple Museum is an architectural masterpiece of the 19th and 20th century. The monastery was erected by Mongolian architects.
The museum is only one block south of the Square. Although not as good as the Winter Palace, there is still plenty to snap. A useful English language booklet is available at the monastery entrance. A concrete ger inside the grounds has a good selection of reasonably priced souvenirs, and probably the best range of books about Buddhism and Mongolia in Ulaanbaatar.
In July 1921 in the center of Ulaanbaatar, the 'hero of the revolution', Damdin Sukhbaatar, declared Mongolia's final independence from the Chinese. The Square now bears his name and features a statue of him astride his horse. The words he apparently proclaimed at the time are engraved on the bottom of the statue: 'If we, the whole people, unite in our common effort and common will, there will be nothing in the world that we cannot achieve, that we will not have learnt or failed to do.'
The temple was built between 1904 and 1908 by the 8th Bogd Khaan Javzandamba, and dedicated to his brother Lama Luvsanhaidav. The Museum has a fine collection of woodcarving, applique, embroidery and sculptures, dated as early as the XVII century.
The museum contains precious examples of Buddhist art including the paintings by Ts. Zanabazar, a renowned religious reformer and great artisan of 17th century as well as colorful masks for Tsam Dance ceremony embroidered with corals, bronze statue of gods in erotic poses, silk tankas and many other artifacts.
This monastery is also known as the Museum of Religion. It was the home of Luvsan Haidav Choijin Lama ('Choijin' is an honorary title given to some monks), the state oracle and brother of the Bogd Khaan. The construction of the monastery commenced in 1904 and was completed four years later. It was closed in 1938 and probably would have been demolished but it was saved as a museum in 1942 to demonstrate the 'feudal' ways of the past. Although religious freedom in Mongolia recommenced in 1990, this monastery is no longer an active place of worship and will probably remain a museum.
