If you are interested in Tibetan Buddhism, you can check out the Eight Auspicious Symbols. They are pretty cool. If you are interested in painting a swastika, which is, indeed a Buddhist symbol, then it should be painted turning clockwise. Counterclockwise is not Nazi, like someone else mentioned, but used in another Tibetan religion called Bon (umlaut the o).

There are also loads of Buddhist deities who are awesome and have particular symbols associated with them, such as Manjushri, who wields a flaming sword designed to cut ignorance. A lotus is a good symbol, as well.
