Quantum Etch
Quantum probability drawn as a living topographic etching — animated iso-contour lines of |ψ|² with bright nodal curves — that you sculpt with walls and wells, then fire a wave-packet through to watch it tunnel, interfere, and settle into shimmering scar-line figures.
∑|ψ|² ≈ 0
tap = fire a packet
The etching is already alive and silent — Begin lets the wave's own spectrum sing.
