Box Kite Things???

[Brutalsleeper]

Hey just a small question here. On the campaign (And maybe mulitiwinia as well) I have notice these things rising from the ground, they look like normal souls but have two rectangles round it (one at top,one at bottom) this makes look like some sort of box kite.
I'm really intrigued as to what these are.Are they just fancy decoration or do they mean something?

I doubt it is of any importance but I'm still very interested.

Its a tribute to souls that have departed back to the source
