Movie A-6. Shortening experiment

Movie showing a series of cut-out 3D views after 7 cm of shortening. The area covered by X-ray CT analysis is shown in Figure 5 (see accompanying paper). The successive horizontal sections show clearly that the transfer zone (lateral ramp) roots at the basal viscous layer and has a shallow dip. Each of the 31 movie frames is a perspective three-dimensional cut-out view that was constructed from a 3D volume consisting of 88 serial cross-sections. Longest dimension of view is 20 cm. Viscous PDMS = reddish grey, quartz sand = orange, corundum sand = dark yellow.
