Mills' Mess caught and is holding a ball), the Mills Mess pattern is sometimes called "Inside Out" -- from its appearance when performed: alternate chops alternating from "inside the pattern" to "outside the pattern", making it seem almost as if the balls are juggling the hands. The effect is that of a juggler frantically pursuing the balls in their staccato movements. The American artist, Glenn (with no last name) aka "The Great Bongo", gave this pattern its name, and claims to have taught hundreds of jugglers "how to do it the easy way." Mills Mess is a shape distortion involving crossing and
All-pass filter same angle but have reciprocal magnitudes (i.e., they are "reflections" of each other across the boundary of the complex unit circle). The placement of this pole-zero pair for a given formula_9 can be rotated in the complex plane by any angle and retain its all-pass magnitude characteristic. Complex pole-zero pairs in all-pass filters help control the frequency where phase shifts occur. To create an all-pass implementation with real coefficients, the complex all-pass filter can be cascaded with an all-pass that substitutes formula_14 for formula_9, leading to the Z-transform implementation which is equivalent to the difference equation where formula_18 is the
