This company is selling custom 3D camo that attaches to all types of ghillie suits (and equivalent). They do not say what the camo objects are made of but I would assume it is some type of foam (the objects are almost weightless).

The causal observer will only see a sniper killed by a pile of wood.

Cleverly disguised as a rock monster. Half man, half rock.

In all seriousness I think this is a very cool product. I am not sure if military snipers need such a product.
