Eye Torture

So yesterday my father and I finally got to start putting down the floor in the basement. There is a plastic 'dimple wrap' which goes on the concrete (below the laminate floor) to protect the laminate from moisture and it has a great effect of making you dizzy if you stare at it. So I'm sharing the effect here with everyone — hope you're sitting down.

For scale, the area shown in the photo is about 5'×3'.
