Multiplex throws are generally grouped into different categories: Stack, Split, Cut, and Slice.
In the case of triplexes, a split can result in one or two balls being caught in the opposite hand.
This terminology can be applied to either the stack, split or cut duplex types of throw.
So, a vertical stacked duplex refers to two balls being thrown together, one above the other in the air, and caught together in the same or other hand.
Siteswap notation is a way of writing down a key feature of juggling patterns: the order in which the balls are thrown.
Claymotion is a style of multiplex juggling that was developed by British juggler Richard Clay in the early 1990s and was first given the name 'Claymotion' by Erica Kelch-Slesnick in 1997.
Emphasis is placed on the graceful movements of the arms and so throws are typically low and controlled.
