This Puzzle was designed for a game that in the end could not be completed, "Empty code". It is a music box that you will only be able to open by using your perception, visual acuity, skill, perspective...
The final test is an elegant game of Chinese shadows projected on a scroll that you will be able to see only if you manage to leave them in their correct position. If you solve all the integrated mini-puzzles you will discover the enigmas it hides.
The dots indicate the time frame of the animation in which that part of the box is used.
