Mermaids!
/Before anyone asks, yes, I worked on Pirates of the Caribbean On Stranger Tides and no, I didn't have anything to do with this scene. Well, we *might* have done a peg lag replacement or two, I don't recall, but the mermaid sequence was done at another visual effects facility. Now that that's out of the way, check out this awesome MOC by TheBrickAvenger from one of the best (if rather unorthodox) sequences of the movie, that lighthouse is perfect! Some dioramas make you want to stand back and admire from a distance, others make you want to jump in and PLAY. This one is in the later category.
Monet painted his garden many times, exploring changes in color and time of day. Meredith Najewicz follows his lead, rebuilding the LEGO Art Water Lilies set with a darker palette and some creative part substitutions to cast the lilies in a different light.
