If, by putting your foot in the river, you change it (a simplified Heraclitian view let’s get behind for now), then the moment Messrs. Rand and McNally have proofed, re-registered, color-corrected and printed their work, it begs for revision because you did (and, honestly, how could you not?) dislodge a pebble in the Arno that later that month arrived in the Ligurian Sea. Not to point fingers. Unseen tectonic plates with their restless-leg syndrome always in a constant war between the hot and the cold are on slow-motion collision courses smashing into one another or splitting apart. Fair warning to the innocent people of the Cascadia Subduction Zone better known as the Pacific Northwest: the Juan de Fuca Plate is headed right for you! A map-changer for sure. Last year a typhoon left Pohnpei for Palau to rearrange the Philippines and, riding the rising South China Sea, visit Vietnam (all in only five days) making a real mess of somebody’s map. On just an ordinary day such as this, Coral Gables might borrow a cup of alluvial sand from its neighbor way up the road — never intending to pay it back.  Or a new kind of führer could move a border, erase your country! My map has Yugoslavia — vanished now — but I have been there so where was I? And the “Russian Empire” figures largely on the Map of the World circa 1914 proving — once again — the plus ça change concept, which actually was invented by Heraclitus. Imagine this, if you will: a chip embedded in your ear that creates a holographic map dancing in the corner of your room, modifying itself moment to moment, showing in real time your foot pestering that pebble, sending it off on its voyage to the sea. Its geographic features — all the pretty-colored countries, rivers, mountains, seas — pulsating like stars in the velveteen midnight, in and out, on and off — and the Ukraine beginning to vibrate from gunfire and maybe Atlantis floating back to the surface like icosahedral advice in a Magic 8 Ball with its blue-dyed alcohol ocean. Imagine that.
