Pi Grid is a direct articulation of the first 49 digits of the infinite number pi. It has 7 rows of 7 columns. Each circle is approx. 5” in diameter. Here, each number value was assigned its own color. Blues are odd numbers, reds are even. Values 8 and 9 are the darkest. Lower values are diluted in color. 1 is clear. Zero is omitted. Parts are attached to form one solid grid.
