The plant man.

The spots in the junctions are just deception of your eyes.

The two floors has got be unconnected.

The two lines are parallel to each other.

The two lines are parallel to each other.

The two lines in the middle of each figure are not sloped.

The unknown faces of nature.

The vertical red bars are parallel.

The width and the height of the hat are the same.

There are no curves in the diagonal lines. (The image is Copyright A. Kitaoka)

There is a movement from the edges to the inside. (The image is Copyright A. Kitaoka)

There is a perfect square in the middle.

There is a skewed square is in the middle. (The image is Copyright A. Kitaoka)

There is not exit.

There is one more gazelle within the branches

There seems to narrow at the tips

These lines are not bent?

They are gonna get really tired!

They are identical shades of pink.

They are not expanding. (The image is Copyright A. Kitaoka)
