Shape dynamics of actin waves viewed on a substrate-attached cell surface. Wave images have been recorded from a single cell of Dictyostelium discoideum at the indicated times by spinning-disc confocal microscopy. During propagation of the wave, the cell showed negligible net movement. The images are color-coded and superimposed on top of each other. Shape changes within a period of less than 2 minutes are best recognized by comparing the green and white images. Waves can fuse or they may split into two as in the red image at the end of the recorded sequence. The images are taken from Figure 1 in [5].
