What exactly is 'box pleating' ?
Can someone give me an exeample and/or diagram of a model which ilustrates that concept (or should I say technique) ?

a style of folding characterized by all folds running at multiples of 45Â°, with the majority running at multiples of 0Â° and 90Â° on a regular grid.
A very long article about box-pleating by Marc Kirschenbaum can be found here: http://contract.home.pipeline.com/ELIAS.htm
An example-diagram would be Jeremy ShaferÂ´sStar of David or Mario Adrados NettoÂ´sDama.
You can try this out for yourself by first precreasing a square into eighths, both vertically and horizontally. Take the square, and pleat it together like a fan, with the coloured side on the exterior. Hold the fan shape in the upright position, looking at the white side, and grasp the top two original corners. Pull these corners apart from each other, and begin to fold them in half along their diagonals. These folds should terminate at the first interior crease (which in this case is 1/8 inwards). Next, bring the top edge down. If you turn the model over, and treat the interior rectangle as in the previous steps, the top corners of the square will begin to become distinct appendages. Repeating this iterative process until there is nothing left to stretch, will give you two long appendages on top, and a fan-like appendage at the bottom. It is noteworthy, in this instance, repeating the stretching procedure on the fan-like appendage will result in the equivalent of a waterbomb base sunk into fourths.
