Falun Dafa is a system of exercise, meditation, and well-being in general similar to Tai Chi. It was introduced in China in the early 1990's, and is differentiated by similar practices by including teachings on morality. Many practitioners have been tortured and killed by the Chinese government due (evidently) to the spiritual nature of some of their teachings. The Falun Emblem is described on this page on FalunDafa.org.
