The 3D map with simulated rain is located in the Maramec Springs Museum in Meramec Missouri.
"The Maramec Museum (pictured above) houses natural and cultural history exhibits. A twenty-one foot bluff, waterfall, and five-hundred gallon aquarium greets the visitors as they enter the museum.
Once inside you will see a rain model with lightning, thunder, and a cool afternoon shower. Displays show the native wildlife in their natural habitats. History of the Iron Works is explained using working models and displays.
While in the museum be certain to view the video "The Hidden World Beneath Maramec Spring Park". This seven minute video will take you into the Spring's cave to view the rare Southern Cavefish and Salem Cave Crayfish in their natural habitats." source (
