Dynamics of the piecewise rotation with two atoms.

The generating map rotates the half-planes about the points S0 and S1, respectively. The resulting systems is a piecewise isometry with two atoms. This java applet works best on a fast (>300MHz) PC running Windows95(8) in the browser Netscape verion 4 or newer . On other machines, the interface may not be perfect and the computation time of a picture can be much longer on non-Windows platforms.
