The Falun Emblem is the symbol of Falun Gong, a new religious movement in China.
The Falun Emblem is a representation of the falun itself and also a miniature of the universe. It represents the pattern that those with supernormal capabilities always see in the falun (though its colors can vary). It consists of five swastikas and four yin-yang symbols within two concentric circles. It is intended to appear as if it is rotating, as the falun always is.
The swastikas represent "the Buddha School" and are also traditional Chinese symbols of good fortune. Moreover, Li teaches that a swastika signifies a Buddha's level and "the higher a Buddha's status, the more symbols a Buddha has."
The four yin-yang symbols (Taiji) represent the "Tao School." Their color has special significance, which Li explains this way:
What we generally understand is that Taiji is made of the two substances of black and white, the qi of yin and yang. That notion comes from a very low level, as Taiji has different manifestations in different dimensions. At the highest level, its colors manifest in this way. The Tao that we commonly understand has this red color at the top and this black color at the bottom. For instance, some of our practitioners’ tianmu [third eyes] are open, and they have discovered that the red color they see with their flesh eyes is green in the adjacent dimension. In other words, colors change from dimension to dimension. The Taiji with the red color at the top and the blue color at the bottom belongs to the Great Pre-Taoism, which includes the cultivation practices from the Qimen School.1
