A clepsydra is an ancient water clock, a way to tell the passing of time in its earliest form. It relied on the controlled flow of water either into, or out of, a vessel where the water lost or water remaining, would be calculated in relation to the passage of time.

Here, there is deliberate play on this notion, via the materials and processes chosen. There is melting, there are holes, it would struggle to work efficiently……. a metaphor for earth’s climate crisis perhaps?
