It is a simple gesture, almost a game, to create a hiding place for the light by folding and gluing the top of a sheet of paper which, nevertheless, overcomes this constriction by freeing its shape more and more downwards. The result is a blanket that rests on the ground, protecting the light source.
It's an interesting experience to conceive the shapes that are created "by casting" and that allow nothing to shine through. Guiding the light is precisely the strong characteristic of this almost sculptural design.
