I was looking for the same thing about ingenius cache disguises I've never actualy encounterd any of these yet but I've seen them up for sale on ebay and stuff some are disgused as flowers, light reflectors, hornets nests, bird nests, a crow, mouse, butterfly, cockroach, spider, rocks, pincones, pieces of wood, chestnuts, leaves, mushrooms, beleve it or not a light bulb, survayer stick, bolts and nuts, eletric outlet covers, a water faucet. There are probably many more that I haven't listed but this is what I've seen. I'm hoping I'll be able to build some and stump the people around here
