Extension of the history visualisation of the dejong system into 4D illustrating the change of the attractor's shape as two param's are systematically changed. One param value is mapped to color and z-value, the other to time creating a movie-like sequence.
Mouse click on any of the buttons creates new attractor from random param's and scans trough the respective param's.
