a chaos generator like Wogglebug
no - wogglebug is random not chaotic - so not a chaos generator
there's a difference... both produce "unpredictable" results but in different ways
random is as random as possible - usually pseudo-random, as the generator needs to be seeded, if using a processor to generate your random - you may be able to modulate the upper and lower bounds or the seed, but it's still random
a die roll is random - it will generate a number between 1 & 6 with an equal probability - let's call it r
whereas chaos will have some sort of rule - or an attractor - essentially a function - to influence the outcome - f(r)
possible very simplistic rule (attracts to 3.5ish) if more than 4 subtract 2 if less than 3 add 2 (3,4,3,4,3,4)
or if a product of 2 divide by 2 - so you get (1,1, 2, 3, 3 , 5 )
roll the die and apply rule
often the previous chaotically generated number will be used in the function to generate the current chaotic value - in order to give a more similar result - or maybe an lfo will be used to influence the outcome - possibly with speed and offset as modulateable parameters or possibly both strategies will be employed simultaneously
obviously these are incredibly basic examples - iirc there's links to much more in depth discussions of chaos on the nonlinearcircuits website (iirc Andrew the owner has a phD in designing chaotic circuits)

Utility modules are the dull polish that makes the shiny modules actually shine!!!
