Did your description include a triangle?

There is no triangle in this optical illusion.

Most people see a triangle, even though one does not exist in the optical illusion. The eye sees clues which suggest a triangle exists and fills in the rest. This is an important feature of our eyesight. Otherwise, we would have difficulty identifying anything that was only partially visible.
