Stout and Square

In the Who Knew? department, Freddy Heineken, yes, he of the beer-brewing family, was quite the visionary and environmentalist. In 1960, he returned from a trip to Curaçao with the idea of making squared-off beer bottles that could be reused as bricks. As with many such individuals, though, his invention, while beautiful and creative, never took off, but it did inspire others: http://blogs.smithsonianmag.com/food/2013/05/when-heineken-bottles-were-square/
   Many of Heineken's bottles were put to good use, and as he had intended, as the building blocks for a Buddhist temple: http://www.treehugger.com/sustainable-product-design/buddhist-temple-built-from-beer-bottles.html
