Parity: Map Dance

A contour map breathes at the centre of a HUD sheet. Two summits orbit in mirror image and pass through each other twice per loop, so the isolines split, pinch into a figure eight and merge again. Around it the instruments keep time.. tiles flip in diagonal waves, a radar sweeps, a globe carries a flight, a table scrolls. Every line is drawn as marching dashes, and the mirror never breaks.
