On the morning of the opening ceremony, we placed a 9 x 9 x 9 foot cube of ink-ice on the China Millennium Monument plaza, and allowed it to melt under the summer sun and wind for three days.

The ice block was made from smoke ink of various densities, the totaled weighed 27 tonnes. As the temperature warm up, the stacked ice bricks melted into its context, volcanic cavities dissolving into pools of still dark water. 

In three days time, the solid entity had entirely disappeared, the residue left behind are only charcoal black inprint on the ground. The abstract symbols vanished, and a space for imagination is all that remains.
