Actually, the passing pattern (or siteswap notation) of Mills Mess (note the correct spelling - no "'") is exactly the same as normal cascade's (or fountain's). The trick is how you move your hands; cross right over left, uncross, cross left over right, uncross, do the cha cha chaa and back again... Mills Mess isn't only a juggling trick as it can also be done with devil sticks, and probably with many other props.
