4 pieces. Every card is running; touch it.

  1. Pin Screen Object · The pin-art toy, as a surface. Press a word through polished pins under a raking lamp, drag it, wipe it, or shake it flat. Your hand is the mould.
  2. Filings Object · Iron filings on paper, magnets underneath. Thousands of slivers swing into a real field and write a hidden word in iron, lit from one lamp. Your pointer is one more magnet.
  3. Ferrofluid Object · Ferrofluid in a dish. It gathers toward the pointer and erupts into sharp spikes, then melts back into a trembling puddle. Your pointer is the magnet.
  4. Chladni Plate Object · A black plate on a shaker, strewn with sand, with a frequency knob. Turn it onto a resonance and the plate sings: the sand walks off the parts that move and gathers on the lines that stand still, and the plate draws its own figure.
