Final pattern

Algorithum

I started with a square piece of paper and a grid 29 squares by 29 squares.  Starting from the top left corner I used 5 patterns.  The first was going across 3 squares, down 1 and drawing the right half of a circle.  Next was going across 4 squares, down 2 and drawing the bottom half of a cirlce.  The third was going across two squares, down 4 and drawing the top half of a circle.  The fourth going across 4 squares, down 4 squares and drawing the left half of a circle.  And lastly going across 3 squares, down 5 and drawing the bottom half of a circle.  I then rotated the page and drew half circles in the above patterns starting from each of the 4 corners of the paper.  I then cut out all the circles and put a gradient behind, making the circles stand out.
