"Letter" is a proximity activated interactive mirror created by the collective Liu Dao 六岛 (art direction: Wu Yandan 吴艳丹 & Tom Lee Pettersen). As the viewer walks by an antique wooden mirror, his reflection triggers another one: a woman seeking help, trapped in the mirror. Liu Dao’s approach to technology is one made upon his thoughts towards the great change in Chinese culture during the last decade. Liu Dao shows a tension between the traditional living conditions and the most advanced technology of which China is the cradle. With this work made out of wood and LEDs - the old and the new hightech - Liu Dao displays the traditional family values and the newly constituted relationships holding it together, revealing the very personal struggle he encountered while developing his own artistic identity.
