Picture 1 - 3

Picture 4

If you click into an ellipse all ellipes will change into dynamic oscillation (picture 1-3). The oscillation keeps on as long as the mouse does not leave the picture.

If you renewly click into the area of an ellipse during this oscillation the movements become slightly increased. But if you a free area all ellipses will be changed into rectangles (picture 4). As long as you do not hit again a free area the dynamic rectangles will not disappear.

Leaving the picture with your mouse will stop immediately all oscillations. Ellipses become shivering for some moments. Afterwards the picturce remain stable.

Colorizing

If the picture is stable and you click into a free areas without ellipses then you will get a colorized picture.

Also colorized pictures show the same effect as above in picture 1-4.

Moving the central axis

If you position your mouse cursor into the central axis during the stable phase of the picture you may shift this axis up or down by drag&drop. The shape of the picture will then slightly change.
