Matrioska is based on the idea that there are overlapped layers in the things we see.
What we see in front of our eyes is often not more than the first image, the most immediate of many others behind it. This state of constant discovery, this curiosity about the images presented and their mutation is what we want to convey. What's behind that? What's inside this? What's that shadow? Is there someone inside it? What language does this singer sing? What's hiding beneath this shape?
