Origami – Paper Folding


The Fibonacci sequence can be used to produce a Fibonacci spiral. This spiral is used by artists as a close approximation to the golden ratio when composing artwork.

Fibonacci numbers are a sequence, published in a book for Western European audiences by Fibonacci (Leonardo of Pisa) in 1202, although a version had appeared earlier, in Sanskrit (200 BC). Apparently, you can see the pattern in ferns, pineapples, and pine cones.

The next number in the sequence is created from the two preceding numbers.
1 1(+1) 2(+1) 3(+2) 5(+3) 8(+5) 13(+8) 21(+13) 34(+21) 55 89 144 233 377
