This is part of the Kina Shell sculpture made of fibre-glass reinforced concrete. It was installed in 2012 in our waterfront. Do I like it? Not sure as it does not inspire me.
Okay! It's strange but they looks like eggs of aliens waiting in the some caves for trigger event to start the capture of earthlings! That could be a fram from a good movie! ;)
I'm not too fussed about the sculpture either - but your photo is great :) I think if they left the spiky bits on it would be a lot more interesting. (and dangerous). I have no idea where this is.
I like your photograph, but I think the color is what makes it uninspiring to me as well. Perhaps a shot of the whole sculpture could pull in a blue sky or clouds and give it some life.
@kathiecb That is what I found in the net "Evechinus chloroticus, better known as kina (from the Māori name), is a sea urchin endemic to New Zealand. This echinoderm belongs to the family Echinometridae and it can reach a maximum diameter of 16–17 cm"
