Remember your own signal

Each person sees a different abstract line. Study yours without showing the others.

This replays one fixed example, not a live session. Nothing is saved. Open the activity to make your own result.

Read all three steps
  1. Remember your own signal. Each person sees a different abstract line. Study yours without showing the others.
  2. Draw once, then seal. Make one continuous stroke from memory. Everyone’s strokes stay hidden until all three are sealed.
  3. Reveal your shared emblem. The three strokes meet in one geometric artwork. Save the result or begin another round.
