Finally managed to go see the Unilever Series latest installation at Tate Modern the other day, by Ai Weiwei - "sunflower seeds".
The floor of the Turbine Hall is covered with literally millions of life-sized sunflower seeds hand-crafted in porcelain.
"Sunflower seeds invites us to look more closely at the 'Made in China' phenomenon..."
It was amazing to see this this carpet of 'seeds' - and it was a very interactive sculpture. Check out the link for more information and the whole philosophy behind this installation.
