Butterfly (Robert Lang)

Lang uses a highly mathematical approach to crease patterns to ensure perfect wing structure and bilateral symmetry from a single sheet of paper. This precise allocation of paper ensures that both the upper and lower wings are proportionate and structurally sound.

Yes, using two-toned or gradient paper is highly encouraged, as it highlights the intricate wing structure and highlights the model's meticulous symmetry. A paper with different colors on each side will bring the realistic patterns of the butterfly to life.

This model represents a pinnacle of origami artistry and is considered an advanced-level fold. It is specifically appreciated by experienced origami enthusiasts who possess the precise folding skills required to execute the intricate wing details.

Yes, as a pioneer in computational origami, Lang relies heavily on mathematical algorithms to map out the exact placement of veins and wings before folding begins. These crease patterns allow him to achieve a level of realism in the wing structure that is impossible with traditional methods.
