三孔

How many possibilities can the three circles in the center of the page create?
This book depicts them as three holes in a wall, with the front and back of a piece of paper becoming the front and back of the wall, creating surprises through the interplay of front and back as you turn the pages.
The circles turn purple and blue? It turns out to be the shirt and pants of a woman passing by.
The circles turn into a face? It turns out a passing dog poked its face through!
The circles turn pink? It turns out cherry blossoms are falling.
By integrating with the book's structure, planar geometric shapes gain another way of being imagined (the cover also features three real cut-out holes!).
