Nets which can be folded to 2 distinct boxes
From one unfolded pattern, you can make two different boxes!
In the 3D window of Pepakura Designer, you can see two boxes with different shapes.
However, the unfolded patterns shown in the pattern window is exactly the same.
This very interesting fact was researched by Prof. Uehara.

Using the animation function in Pepakura Designer, you can watch how the same pattern transforms into different boxes.
