Tonight I finally found out how to play a rhythm I had been processing in my head for weeks. One night I had thought of this way to play a simple rhythm in my left hand, but put dotted 8th notes on top, so that they only line up every third measure. The rhythms weave in and out of phase, and the feel almost shifts from 4/4 to 9/8 in places. The result is very complicated, and I had to practice for hours.
Here is a recording. (1.2 Mb).
While listening, can you break down what rhythm each hand is playing? These and other audio clips will sound better on headphones than laptop speakers.
