Eight bells

Distances are squeezed so all eight fit; the angles are real. Each bell is the planet's own orbit, raised by whole octaves until you can hear it. When a planet laps faster than its bell can ring, the laps blur into a steady tone whose pitch is the number of laps a second, and faster still that tone climbs out of hearing; the count always keeps the true number. Past the year 3000 the orbits hold their last known shape, so only the lap counts mean anything.
