C6 - Attraction into a chemical core - variation 1

The spiral wave observed in the Belousov-Zhabotinskii reaction turns around the center of rotation once every eighteen seconds. Thus, a sequence of six images taken in three-second intervals covers exactly one rotation. Since all images are stored as digital data arrays, they can be superimposed in a way such that at every single point of the image only the maximum concentration measured will be displayed. Through this technique, an important feature of chemical spiral-structures is visualized within a single image - the wave-amplitude declines towards the spiral center. A “concentration well” is formed, which remains steady at its center by interaction of diffusion and reaction.
Picture C6 shows the spiral core in 3D perspective, where the viewpoint of the observer is located above the concentration maxima.
