The strange pattern was clearly man-made. In older imagery from Bing and Nokia Maps taken prior to 2004, the strange pattern wasn't visible, indicating the shapes appeared more recently.

As the researchers did so, they found that hexagonal patterns of grid-like activity emerged spontaneously in the computational units—just as they do in the brains of real rats in lab experiments.

This quirk is apparent in an interesting set of visualizations that display the relative dominance of the North-South-East-West grid pattern within the road networks a handful of cities and ...

Many cities around the world also have grid patterns highly visible from above, ... The units of length are different, of course, but it’s interesting that the grid is 6 by 6 units, ...

In 1970, British mathematician John Horton Conway created a zero-player videogame, dubbed "Conway's Game of Life". The game takes place on a grid of squares, and the only input a user can have is ...
