Lucy Hibburd, of Falmouth College of Arts (UK), made a project aimed at raising awareness about genetic modification.

Each of her four postage stamps shows a beautiful, yet disturbing image. A leaf represents the environment, a flower stands for crops, a butterfly for wildlife, and a tomato for food. But each of these images has been modified to mirror the square shape of the stamp.

The reverse of the stamp carries a message thanking users for taking part in the experiment although users are unaware of what this means until they lick the stamp and coloured dye is transferred to the tongue – highlighting how one is drawn into GM experimentation without being aware of doing so.
