Undersea sculptures

Jason deCaires Taylor has for many years been planting undersea sculptures like this one at locations near enough to shore that the occasional swimmer or snorkeler will encounter them.  (The sculptures are so constructed that as coral colonizes them they become nifty fish habitats.)  Sounds like a great Windsockers project to me.  Check out his website for many great pix:   http://www.underwatersculpture.com/
