Hi all,
I'm trying to reproduce this image (below) using particles but having trouble recreating it. It's one of those things that seems like it should be pretty simple to recreate but I'm at a loss. Hoping to get some feedback on the ideal way to get this to work.
Like the picture shows, particles would emit from the center of the screen and travel fairly slowly along the Y axis. I'd appreciate any help. Thanks

Ignoring the large circles for a moment, could you set up (in Particular) a grid emitter with 100 x points and only 1 y point? Then, use a by-directional emitter, or just run two copies with one flipped. Depending on how you want the particles to react, you could use Air to slow them down after emission, Wind (or just Velocity) to give them a constant velocity, or Gravity to have them speed up.

For the large ones, you could create another similar Particular instance to handle those.
