Studying Buddhism. Here's a great Prezi from a college professor about the development of Mayahayana Buddhism in China. It's long and includes several video clips but you could certainly adapt parts of it.
I particularly enjoyed the early part of the Prezi about the role of trade routes like the Silk Road in the cross cultural transmission of Buddhism. In another section, the author reviews the significance of the Dunhuang manuscripts, religious documents from the 5th to 11th century.
