I'm iterating this function (attributed to Peter de Jong) a number of times: x<sub>n+1</sub> = sin(a * y<sub>n</sub>) - cos(b * x<sub>n</sub>) y<sub>n+1</sub> = sin(c * x<sub>n</sub>) - cos(d * y<sub>n</sub>) whilst logging the frequency of hits in a given coordinate. When I'm satisfied I plot the pixels using a logarithmic weighting to control the brightness of each position. The source code can be found underneath the applet. Thanks. I’m iterating this function (attributed to Peter de Jong) a number of times:

xn+1 = sin(a * yn) – cos(b * xn)
yn+1 = sin(c * xn) – cos(d * yn)
