I would like to share a thought that popped into my head.
I think it is good to look for inspirations in nature so when I think about this project as connections with others via the crystals, it reminds me a shoal of fish or murmuration of starlings. Single individuals forming the shoal follow the same general direction but each fish may do as it pleases (and there is a suggestion to sing or read to the crystals not obligation). But it is more probable that fish not following the group are prone to predators attack. The primary advantage of forming a shoal is to minimize the chances of being eaten by predators. A single fish would have to face a one on one battle for survival if a predator shows up. In a shoal, fish can use the intelligent solution of a coordinated defense to avoid and confuse predators.
If the whole group with their crystals would do the same thing at the same time, or even not exactly at the same time but continuously and cyclically (birds or fish also move and react one after another, not all of them at exactly the same moment) I think that the whole group could be seen by a larger scale observer as one organism. Similarly as flock of fish reminds us one moving organism despite that we know it consists of hundreds, thousands or even millions of fish. In my opinion, by doing so (making an attempt of highly symbolic unification) we could be sending a message to the Universe that we would like to follow the path leading to union with the One. Maybe by this kind of symbolic actions we are choosing our orientation and as a result, our "future".
Just a thought. FWIW
And here is an example of starlings forming a shape similar to a human ;)
