The exterior wall of the Mirror House in Hanoi’s Reunion Park was decorated with ceramic mosaic murals of Truong Sa waves. Thu Thuy’s idea aimed to promote the beauty and power of the Vietnamese seascape. As a visitor approaches the Mirror House, there is a sense of mist from the ocean as this entire wall of the building is covered with shimmering waves created entirely by 300,000 ceramic mosaic tiles, giving the installation a feeling of unity and wholeness.
