No idea if this will work or not, so I may immediately take this down… But!
Underwater sculpture in Grenada by Jason deCaires Taylor; all of his work is amazing, but this one I particularly love. This piece is Vicissitudes, and it commemorates the African peoples thrown overboard the slave ships in the Middle Passage. The link to the gallery is here: http://www.underwatersculpture.com/pages/gallery/vicissitudes.html and I recommend viewing it; there are close shots of the sculptures, and you can see the coral growing on them. Incredible.
