Juggling Lab vs Ham Learning

Juggling Lab is an application for creating and animating juggling patterns. Its main goals are to help people learn juggling patterns, and to assist in inventing new ones. Quick feature overview: - Animate all solo and passing siteswap patterns, including synchronous and multiplexed patterns, and patterns involving movement of the juggler bodies - Support for bounced throws - Realistic hand model, with cubic spline hand paths that match the velocities of balls at throwing points - Integrated siteswap pattern generator - Step-by-step instructions to learn popular patterns - Huge (400+) categorized list of juggling patterns - Bookmark your favorite patterns - Pinch to zoom, rotate, pause and change the speed of the animation - Add, delete and rename pattern lists and patterns - Share patterns and pattern lists with your friends - Interoperates with the Juggling Lab desktop application
