What the Sites Are Drawing III

Lines made of tiles that are not lines

The facets of this gem are drawn by rows of lighter tiles running through the darker ones. None of those tiles is a line; each carries a site’s initials or logo, the same as its neighbours. You read a line anyway, because the eye groups things that are alike and in a row, and treats the group as one object.

That grouping is why you can see the outline and the facets from a distance long before you could say what is written on any tile. Close up, the difference between a lighter and a darker tile is small next to the difference between one logo and the next, so the grouping has nothing to hold on to.
