Button set

The button leans toward the pointer, then settles back with a soft elastic return.

A circle of colour floods the button from where the pointer entered, then drains.

The letters roll up one after the other, from the side the pointer came in.

A stroke draws itself around the button from the nearest edge, then erases.

The button turns toward the pointer in perspective, with a sheen and a lifted label.

Cells of colour light the button from the side the pointer came in, then go dark.

Shards of colour fly out where the pointer struck the rim, and a glow holds.
