Photo — In arc
Prints fanned along an elliptical arc like a garland, their spacing set by dividing the sweep evenly from the first photo to the last.
The photo set is laid out along a curve: each print centred on a point of an ellipse, the first at the arc's start angle, the last at its end, the rest spaced evenly between. With the default half-circle the row bows across the middle of the frame.
There is no motion — this one is pure placement. The arc's anchor, its two radii and its start and end angles are all adjustable, so the same layout collapses into a straight fan, a crescent or a full ring, and a debug switch dots each anchor point for lining up compositions.
