We are interested in periodic juggling patterns during which objects are thrown to different heights. Throws are encoded by natural numbers. We demonstrate examples of juggleable sequences and investigate their mathematical properties. references: Allen Knutson explains it: http://www.juggling.org/help/siteswap/faq.html Jack Boyce's Java program simulates it: http://www.physics.berkeley.edu/research/chiao/ja/ja.html Bruce Tiemann really does it: http://spot.Colorado.EDU/~tiemann/
