    How about flour and water? This reminds me of a joke...

    Active camouflage need only require that you emit the same light passing through. If you have a versatile enough emitter, you could absorb some light to observe and emit the rest on the other side. Thus you can have a perfect active cloak PLUS be able to observe as well. Net energy has to be around zero, so you'll be burning power to run it, but it's better than blindness.

Some people have a great ambition: to build something that will last, at least until they've finished building it.
