Math-Magic Vanishing Space

Inspired from the astrological tables, here is a new puzzle of my creation designed according to the ‘Golden Number Rules’, which is reflected in the proportion of each single piece of the game. Thanks to the balanced dimensions of its pieces, this puzzle acquires some intriguing magical properties!

This “math-magical” puzzle is composed of a tray in which the pieces are assembled.

Fit the small extra piece into the puzzle without apparently altering its original dimensions. All the pieces must lie tight and flat! Impossible? See the solutions below.

The animated demonstration below is more eloquent than all theories. The puzzle shown in the video is a variant made in hard plastic, and cut using water-jet technology with an accuracy/precision of 0.01!

I am looking for a game manufacturer able to produce and distribute this incredible puzzle. You can contact me through my website.
