This modular direct paper sculpture is part of an ocean-life series."Urchin" is inspired by animal/flower-like ocean marine-life. It is constructed only of hand cut, hand folded, archival color, inkjet paper modules and Ph neutral glue. There are approximately 2800 triangular double-pocket, double point modules of paper linked together. This is an ancient Chinese paper folding technique called "Zhe Zhi." The architecture of folded, linked and glued paper units creates a very strong and durable sculpture medium which permits direct paper sculpting. The science of topology dictates the slope and curve of the surface by the number of points linked in a circumference. Archival paper is acid-free, color stable and generally used as legal substrate for documentation and suitable to last a minimum of 100 years.
