Hi, Can you please tell me who created this model and what's its name?: https://fbcdn-sphotos-f-a.akamaihd.net/hphotos-ak-xaf1/v/t1.0-9/10325274_1119380458077931_2279331049175836542_n.jpg?oh=223c9581dce26b371dc93ed392ace869&oe=55E8340D&__gda__=1441632186_5e5d32b0cf47de947da9ac662cae6136
It's made from a duocolor isosceles right triangle, and you simply fold the same tip in half over and over and over. At the end you get smaller and smaller overlapping isosceles right triangles. Can you also please name what mathematical, geometric, trigonometric... principles are exemplified through this model? Thanks in advance ; )
