LEGO Level 9000

[Thorin]

I have a lot of LEGO in my house, and I've spent a lot of time building with my little guy.  We have several sets with 2000+ pieces, and we've done the LEGO Death Star (3,803 pieces).  But never, ever, have I seen someone design a fold-up LEGO set that folds without coming apart.  Until now: https://youtu.be/NQZRy3nKwNQ

Production period is about 15 months.
The number of used parts is unknown.
Weight is about 12.5kg.
The adhesive does not use.
Size at the time of storage, the length of about 70cm, side about 70cm, the height is approximately 11.5cm.
At the time of storage decoration, the part was not enough.
In weight measures, it was hardest.

Music is the original song.

The Himeji Castle with a small castle tower, I would like to someday challenge.
Is such as walls and moats and wells, are not positioned correctly.
Some of the actual Himeji Castle of the sarcophagus, remains is probably not included.

Interesting, must have a great interlocking design to have it hold up. I have some sets that have moving parts that come apart all the time
