Lazer system like in concert

Hello everyone,
I’m wondering if someone has an idea of how can I make lazer system like those we see in concerts (cf. the image). But with not using any light. :upside_down_face:

I guess using thinInstances planes with some glowLayer could work maybe

Such as thinInstances planes that have same pivot point, or something like same parent (empty). :thinking:
Sounds a good way to go.
I gonna give it a shot to see the result, then share the playground here.

cylinders might be even easier to do first :slight_smile:

I end up with this result, I think it simulate well the lazer system.

Here is the playground : Playground
