The Chaos Filter is/was a clockable, switched capacitor comb filter built around CMOS chips - there were only a short run made originally, but the module may make a comeback if there's sufficient demand (there's a voltage-controlled version on the drawing board ...)

The biggest issue with this particular design that the output tended to be a bit 'clicky' at lower clock speeds. Even so, it was quite possible to coax some ... interesting ... sounds out of it.

Glitch-mongers will probably dig this one.
