butterflies

morph="butterflies" — paper butterflies (match-morph-butterflies.ts).

Read the rig's notes

The outgoing picture is cut on a grid of small tiles; every tile becomes a
paper butterfly — two wings hinged on its centre line, printed with that
piece of the picture. They peel up toward the lens, their outlines cut into
fore- and hindwings with a dark body on the hinge, and flutter up into a
swirling column (one full turn about the swarm axis, wander, banking, a bob
on every down-stroke). Mid-flight each print swaps to its tile of the
incoming picture; the butterflies glide back down onto their new cells
wing to wing, the beats die out and the wings flatten into the incoming
element. Exact at both ends — flat, unshaded tiles of the two snapshots.
