It all started with a conversation between art lovers. One of those challenges that we set ourselves to activate our thoughts and our imagination.

It was also the beginning of a long period of research and development to play with the laws of elementary physics and achieve the levitation of matter. Until now, no one has achieved this kind of performance, neither in art nor in engineering.
