> Could it be a message? Why to send from place to place a radio signal when we could set up a bunch of planets in an improbable/impossible regular configuration to be noticed from everywhere during a very long time frame?
Intuitively, for signalling purposes, setting up six planets in a weird orbital configuration to attract attention seems like it would take WAY more energy to do. Also, it tells you nothing about how to reply to the hail.
Though I could see it as some kind of solar system-sized monument.
