It’s Labor Day and the nation’s workers are busy in their backyards working on their pig roasts, racks of ribs and barbecued chickens. Some, though, might be slaving over something called a Toynbee Tile.

Toynbee Tiles, essentially slabs of plastic carved with messages and embedded in paved roads, began popping up in the 1980s. They all espoused a paranoid conspiracy theory in a sort of code that no one has since unraveled despite many theories. The tiles are most likely produced by copycats of the original artist, and take a certain amount of ingenuity and devotion to produce–considering that the end product may never be discovered.

So my question of the week is: Are Toynbee Tiles viral messaging and how would they stack up to a modern online viral campaign? Answering this is difficult, but potentially valuable for marketing campaigns. After all, the tiles can’t cost more than $20 per tile in materials, while the buzz created is priceless. As real-world guerilla marketing is supplanted by online campaigns, Toynbee Tiles, or something similar, could garner massive exposure.
