Fibonacci Spiral

I don’t really know what to say about this one now, since I spent all this time recreating the Fibonacci spiral in illustrator, and dividing up the values so I had the perfect 10 equal steps from black to white, then I saw the link on wikipedia for the golden spiral and somebody already used the exact same thing to illustrate the sections. Well almost. They have 9 sections and I have 10. So it obviously isn’t that original of an idea. It looks cool though.

This was the first attempt to figure out how to build it.

In a Fibonnaci number sequence, which goes back hundreds of years, each number is equal to the last two numbers. So it goes 0, 1, 1, 2, 3, 5, 8, 13, 21, and so on for as long as you want to keep adding numbers. The sequence is found all over in nature, so its really more of a discovery than an invention.

One square and curve unit

Creating the graphic wasn’t all that hard, its really a series of squares, with a smooth arc from one corner to the other. You can keep growing it out as large as you want, but I thought 10 would be good for percentages of black. The centermost square is 100 percent white, then I add 10 percent black to the value until you get to 90 percent at the largest square. It never gets to 100 percent black unless the design is on a black shirt.

The end result

Really the best way to build the graphic is to make one square with its corresponding curve, then group those, then duplicate them and scale them as big as you like.
