So, I have this overhead space shooter game I've been working on, on and off, for just over 2 millenia. In it, I have these "space clouds" that orbit the "black hole" at the center of the playfield. See pic:

EDIT: The cloud is pretty hard to see in this pic, but it's there. Trust me!
I was HOPING to add an effect where anytime a player flew through one of these clouds, they'd leave a kind of furrow -- like a car driving through snow.
I thought this might disappear after a moment or two, as the gas of the cloud filled in the gap.
I've tried dropping sprites whenever a ship was overlapping the cloud, and having those sprites inherit the cloud motion... Then adding a FADE behavior so they slowly wink out of existence leaving only the cloud sprite... It doesn't look to great, perhaps it's the sprite I'm choosing?
I also tried playing around with a quazi blob type setup where the "blob" sprites all had a physics component and were tied to an invisible object that made it seem like they were drifing along. Then when the player's ship moves through -- they'd move aside, etc... This looks okay. But not at all like the "furrows in the snow" look I was hoping for. Here is a CAP for that:
That one is using the BlobTest effect from Tulamide that I found on the boards here somewhere, but will now rehost here:
Anyway, that's as far as I've gotten. I was hoping someone might have a suggestion as to another way of achieving this kind of effect.
Any help greatly appreciated--
