A beautiful reminiscence on the power of grids, by Alexander Miller:
“When I was a kid, my dad gave me a piece of paper with a grid printed on it. It consisted of larger squares than standard graph paper, about an inch in size. It was basically a blank chessboard. The columns of the grid were labeled with letters (‘A’, ‘B’, ‘C’, etc.), the rows labeled with numbers (‘1’, ‘2’, ‘3’, …). My dad then helped me draw a map of an imaginary island within the grid’s boundaries. I sketched the squiggly coastline of my island, forming a splattered blob shape, within which I added the obvious necessary features all mysterious islands require: forests of crudely draw trees, a mountain with a cave entrance leading to a secret underground network of caverns, an abandoned hut on the beach. There were variations of this game: sometimes the map was of a completely imaginary place, but other times we mapped a known area – like our backyard – and added fantastic elements.”
