as geocachers we know: very often we search around "zero" and rarely get to the object directly. we turn around in circles.
now there is a coin to illustrate that behaviour. very simple and plain, but still quite amazing. there are two labyrinths, and they join together by a hole in the center.
the front side is plain metal colour (except writing on the top: black), the labyrinth outlines are raised.
the labyrinth channel on the back is recessed and filled with a colour (red, blue glow-in-the-dark (plus epoxy), white-yellow glow-in-the-dark (plus epoxy), matte black, respectively).
labyrinths are different from mazes you cannot go wrong with labyrinths (it is just the longest possible way). the coin’s name is also written in the original language of the word, greek: lab´yrinthos.
