Can you see it?

Open the image in its own tab in your browser (or any image viewer/editor), scale it/zoom it so that the centers of the circles are physically about 60mm (2.5") apart (on regular screens (~100DPI) you can just zoom out to 66%). Then get close until you see a third object in the middle of each pair. The top one is a pit, the bottom one a pyramid.

You should be seeing six.

PS Make sure there isn't a candid camera behind you while trying this.

Of you do this properly you don't need to squint. On the contrary, keep your eyes parallel. The hard part is doing this while focusing on something close, far-sighted people with glasses have an advantage.

Over on gimp-forum.net there is a "pattern" version which may be easier for some.
