* “Simple bowl (32)”*

One folded square sheet of paper, 5" x 5" x 4", 2006.

This is one of the simplest pieces
in my ongoing series of bowls
formed by pleat tessellations. Every fold is a straight line segment
parallel to an edge of the square sheet, and no fold is ever undone.
The curved surface is purely a result of the intrinsic tension in the sheet
of paper trying to unfold itself. This simple bowl is constructed by using
alternating pairs of vertical and horizontal pleats, from the edges
toward the center.

* “Wave (32)”*

One folded square sheet of paper, 10" x 10" x 5", 2006.

**First prize**

The wave is one of the pleat
tessellations that continues to amaze
me even years after I first folded it. The peculiar symmetry and the
tension
caused by locking the edges causes two of its corners to bulge in opposite
directions, while the remaining two corners remain fairly flat.
As in the simple bowl, the pleat sequences all begin at the edges and
proceed towards the center of the sheet, but the difference is that all
horizontal pleats are oriented the same way, and similarly all the vertical
pleats.

I try to fold 'organic' origami,
studying the natural tension
in a folded sheet of paper and how it leads to the final shape.
Most of my work uses only the simplest folds. Working with,
instead of against, the thickness of paper, allows my regular or irregular
folding sequences to shape curved surfaces and lines.
Many of these pieces are discovered rather than designed,
even though I often start by imagining a shape and only then finding
a folding sequence that creates tension in the places necessary
to achieve the preconceived shape.

My pleat tessellations are formed by sequences of pleats whose
interaction causes theoretically flat folds to curve. There isn't always
a repetition of a pattern, or even a regular plane division, yet the term
tessellation seems proper for these pieces.
