Lucie Pauwels wrote about it:

“This puzzle was developed from a smaller puzzle, in a 2x2x3 box, the Minimal Nest, which I made for the Minimal puzzle Series by Frederic Boucher. This puzzle has a box and pieces whith shifted layers. I wondered if I could make a larger version, so I worked on a 3x3x3 shifted box. When Volker Latussek saw this puzzle, he suggested to use the Soma pieces. He send me a couple designs for the puzzle pieces, one of those sets was really nice with characteristic Latussek features,so we used these for the ‘Nested Soma’. Pelikan made the beautiful wooden version.”

The goal of the puzzle is to fit all the pieces inside te box.
