3D glasses deceive us: they render something before our eyes that is not true. The idea that Aldi & Lidl also deceive their customers by selling low quality meat products as top quality ones, made me link the 3D glasses visual to this particular situation. The personificated steak-face might shock the viewer at first sight, but certainly engages him in looking deeper into the issue. After all we are what we eat.

These special 3D glasses can also be used separately from the steak-face, on the users themselves.
