Looking around for some two-way mirror in glass or acrylic (my preference), it is part of a project to build something like these devices - http://michaelteeuw.nl/post/111886383522/magic-mirrors-around-the-world

Just looking for some idea of cost and availability, approached a couple of suppliers but so far no luck getting this in NZ.

Places online like http://www.twowaymirrors.com/ maybe an option but I expect shipping would be risky in terms of getting it here in one piece.
