In 1993, Apple's corporate headquarters sported an icon garden, with large colorful 2D sculptures of some MacOS icons planted in the ground amongst the greenery. The Icon Garden was a fixture on Apple's campus for many years until it was removed in 1998, officially for restoration purposes. However, rumors were that the pixelated icons didn't fit in with Apple's "Think Different" advertising campaign, the upcoming iMac release, and Mac OS X plans, and so they were never put back up.
The Icon Garden lives on at Jory's Apple Icon Garden
site, where there's a virtual tour of the garden and even a Quicktime VR video of the garden. Oh, Dogcow, how we miss your moofiness.
