how make a choreography like this?

before I posted an article to the title like benjamin button but in reality I should make a choreography like this and I have of the characters that make up these colors. will be seen from far away and there is little animation (the cups are). I thought of the particle and then seeing the tutorial that was recommended to me I realized that with the particles does not work.

You have to give me some idea on how to realizzazre a video like this

That’s nothing like the Benjamin Button example. Those people are just holding up square placards that are red on one side and yellow on the other, and flipping them. It would be relatively easy to animate that, though incredibly tedious. But then, training that group of people to do it was also probably tedious, so it’s fair.

I thought of using the particle … but I saw that there is a bug when I use the map density to form particular shapes particles. Particles then use an instance of an animated group
