a very strange sign

here is a completely confusing sign i saw on the edge of a building site. the green goes nicely with the purples, but i haven’t a clue what it means.
it appears to be implying that the people in the middle are the centre of gravity.
perhaps it’s the holy trinity in the middle (God, Jesus, Holy Spirit in that order). The sign is subtly telling people “hey, this God/Jesus/Spirit thing. think about it. it’s the only way of making sense of life”.
i suspect it’s actually an emergency congregation point. which is also how some people think of God.
