15 cards

Knit: A knitted swatch with a rope cable, knitted a stitch at a time; tap to knit a row.
Denim: Denim twill with whiskers, a topstitched pocket and a white selvedge.
Paper: Cotton paper letterpressed with DOT/480; tap for another impression.
Wood: The time carved into a lacquered board whose rings shimmer with the light.
Leather: A pebble-grain leather wallet corner, saddle-stitched by hand.
Sand: A Zen sand tray: drag to rake it, tap to set a stone.
Ice: A frost fern growing on a window; breathe on it to melt it.
Mercury: A pool of mercury: stir it, tip the phone to pour it, tap to split a bead.
Thread: A thread hanging from a spool: pull it out, flick it, tilt to swing it.
Lichtenberg: A Lichtenberg figure burns across a maple plate between two electrodes; tap to burn one to your finger.
Erosion: The time in sandstone, worn by rain all day; each digit has weathered since it last changed.
Frost: A frost window with one snowflake a day, grown cell by cell on a hex lattice.
Kintsugi: A glazed plate that breaks where you tap it and mends along its cracks, one seam at a time.
Mud: A slab of wet clay dries and cracks into polygons, one crack at a time, until the rain comes.
Paper fold: A sheet of paper folds crease by crease into a glider, then opens flat again.
