British banking giant HSBC did a clever thing with a swimming pool: they took a picture of New York City from above and applied it to the bottom to make a point about climate change and rising sea levels. The effect is nothing short of amazing. My eyeballs are still having trouble not believing these people aren’t swimming a thousand feet above the NY skyline. Granted, sea levels would never rise that much — and the water probably wouldn’t be crystal clear (or toxin-free) — but, it still makes you think. (source: groovygreen.com)
