Now this is amazing! York Maze a Star Trek Tribute - UK
Containing 1.5 million individual plants, this maze --just outside York-- covers 32 acres, the equivalent of 15 football pitches, and was designed using satellite technology, which meant the paths could be cut to an accuracy of half a metre. The huge maze was created by Tom Pearcy as a tribute to the 40th anniversary of Star Trek.
