This mosaic was made from 1099 individual photographs of circles, photographed by 265 talented individuals. The mosaic was constructed algorithmically by Jim Bumgardner using images from the Squared Circle photo pool at Flickr, the photo-blogging website. The photographs are arranged in a fibonacci spiral, a fascinating pattern commonly seen in plants, such as sunflowers and pinecones. You will notice spirals going both clockwise and anti-clockwise. If you count the number of spirals in each direction, the result will be two successive numbers in the fibonacci series.

In this image, new images were added at an angle of about 222.49 degrees. The ratio of the whole circle (360 degrees) to 222.49 is 1.618 -- the "golden mean" -- a ratio associated with beauty since classical times.

Here's a closer view of the mosaic. Click on a tile to see the original photo.
