Glass group. Children of one group share a single piece of glass that melts between them when they come close. One backdrop, clipped to the merged outline, so nothing blurs twice.
Press the search button: it splits off and docks back.
Press and drag any piece: the glass stretches along, necks and all.
Drag a drop toward the pill, let go and it springs home.
Morph. A control swells into a panel of the same glass. Each scene below pushes on a different weak spot; slow it down or let chaos interrupt it to see the seams.
Corner. The reference: grows right and down from the button.
Upward. Anchored bottom-right: grows up and left.
Capsule with a label. Pick an option: the button comes back with the new label.
Into a field. A circle into a long capsule, anchored right; type, Enter or Esc.
In a group. Melted to the bar: pours up out of the dock, parts from it, and back.
Over the group. Covers the bar: lifts out as its own glass, the bar blurred beneath.
Squircles. Left: squircle into squircle. Right: round into squircle. Round where corner-shape isn't drawn.
Far. Clear glass, no overlap: flies across the scene.
Edges. Left: barely bigger than the button. Right: tall, narrow, tinted.
