Hector Zamora’s Synclastic/Anticlastic Biennial installation at Mann Island features 170 concrete manta rays suspended (flying? floating?) from the ceiling. Out of the Biennial work I’ve seen so far, this is my favourite.
I visited quite late on in the day and it was completely empty which gave the whole thing a very eerie air – the rays sway very gently in the breeze and it’s vaguely unsettling.
