Do you mean like following the pattern of a line produced by a sine wave?

I came up with the following, where the frequency is around the number of cycles across a 600 pixel wide world: 
int speed = 1;
double amplitude = 50.0;
double frequency = 3.0;
setLocation(getX()+speed, baseY+(int)(Math.sin((double)(getX()+speed)*frequency/95.5)*amplitude));
The first three lines can be instance fields instead of local variables (or even class constants, if desired).
