ワムの折り方がコンピュータープログラムで解析可能になったようです
Please check 'KADO: The Right Answer', a Japanese anime program. A lot of WAMs which are polyhedron origami structures like balls are appeared in that program, and they are too complex and strange to create them. In short words, no one can make them.
I think that your watertight algorithm might be able to create them.
