Check out the Beautiful "stained glass" water tower sculpture by Brooklyn artist Tom Fruin. It's in the DUMBO section of Brooklyn (the Down Under the Manhattan Bridge Overpass area.) It's made of plexiglass and steel.
British Sculptor, Jason deCaires Taylor, creates underwater museums that will eventually create habitats for marine life, and now spread awareness. One of his biggest collections is in Cancun, MX. I can't wait to go scuba diving there!
