In this picture the lines all lead to the end of the tunnel so you almost immediatly focus on the end.

The lines in this picture lead you straight to the bright white door on the front of the house sitting on the water.

These lines are all curving in different ways and you follow the river down until the end of the picture and you wonder where it ends.

The two diagonal lines lead you to the kite flying through the clear blue sky

There is many sets of lines that go through this picture and my eyes follow the curved walkway going up onto the doorway.
