Periodicity is the quality of occurring at regular intervals or periods (in time or space) and can occur in different contexts
Oscillations, waves and standing waves have crests at periodic intervals of space and/or time
Now back to china 1300th century B.C. People felt like needing units to measure length. I dont know how the old chinese decided, but it is know that they cared for harmony. Every building on an estate or farm had its special place. The chinese system was adopted by the japanese people probably near 700 and is known as Shaku.

For me as european it is remakable that the old units are metric periodics.
1 shaku = 303,0303030303030... millimetres
It is also remarkable that the units are connected to sound. The japanese flute shakuhachi translates literally into "Shaku 8" and the flute is 1 shaku and 8 sun in length indeed.
At some point in history the japanese carpenters began to make parquets and boxes.

The patterns have been designed by using shaku units.
A special form of box was the japanese puzzle box. The are build with shaku units as well. Some of them require up to 200 moves to open them.

Of course there is the exeption of the rule.They are designed so that they can be opened only by the creator of the box or its owner. Some boxes rely on a secret pressure point or “kannuki” built into the sides or lid of the box to open them, while others require a precise sequence of consecutive moves to release the internal locking mechanism. Without knowing the precise pressure point or the proper sequence of moves the box will remain securely sealed and its contents hidden.
Although it seems within the context of the boxes this is just an extension of the rules...Some well-known masters pride themselves in making unique boxes that do not follow any size guidelines
Our 3D dimension is a box. Our brain is a box. While it is able to think of anyhting outside the box, it is not able to leave the box on its own. It requires other body parts (and spirits? ) to do so, but that is a different story/topic.
Every intellectual task or challange is a puzzle box. It is about investigating and observing the rules so maybe we are able to open/solve the box.
The modern representative is Rubik's Cube
http://en.wikipedia.org/wiki/Rubik%27s_Cube
Note:
The extreme 4D and 5D cubes are not valid, because they are virtual. They are not 4D or 5D, the computerscreen is only 2D. To think they are 4D or 5D is a brain fart. They are *obviously* 2D and not real but virtual. They may be challanging, but they remain virtual.

Back to Rubik's... Once the cube is solved it opens a gate in our brain. It doesnt matter how we solve the qube. Math, try-and-error or dreamvision are valid strategies. Any solution of a problem opens a gate, so we can leave the room of problem. The movie "The Cube" is showing this perfectly.
http://en.wikipedia.org/wiki/Cube_(film)
The japanese puzzle box demonstrates how we can align a box to vibrations by using particular units or by not using particular units. The movie Cube shows quite well how our decissions on the way to a solution make a difference. In the movie the wrong decission is certain death/disaster.
Which leads me to another famous riddle qube... Lemarchand's box
http://en.wikipedia.org/wiki/Lemarchand%27s_box
Although this qube only exists in pop culture movies and in books from Clive Baker, it demonstrates very well how aligning a box to certain units and how decissions on the way to the solution of the riddle open a mind gate. In the case of Lemarchand's box it is opening a gate into a pain world. Not exactly hell, but maybe worse.
