To my ears, Herbie's solo on Ostinato from the Mwandishi album is exemplary to what he explored on the Rhodes rather than the acoustic: The Rhodes' color, resembling African xylophones, inspired him even more to rhythmic/percussive patterns in which harmonic aspects were less important. You can already find this on Inventions and Dimensions, but from the sextet albums on this really blossomed.
The solo on Fat Albert Rotunda is another case in point, with lots of call and response patterns.
