We came across a visualization of Pi you won't believe. Pi represents the ratio of a circle's circumference to its diameter, and is an irrational number, which means the places after its decimal point extend into infinity. And this image, created by design studio TWO-N, approaches just that.

TWO-N designer Hermann Zschiegner created this interactive image after Japanese PhD student Shigeru Kondo calculated the world record 10 trillionth decimal place of Pi in Oct. 2011.

At 4 million digits, Zschiegner's image only represents a fraction of all the known decimal places of Pi, but we're still impressed. "We are representing 4 million digits at a glance," Zschiegner tells Mashable. "It would take an average person roughly three weeks to read out the numbers, but it only takes a second to look at our graphic."

Each number in the image was given a different color. That's why you're able to distinguish a separation in the image, despite the digits being shrunken to near minutiae. "There is no pattern, no order we are aware of in this string of numbers. They are random, white noise really," said Zschiegner.

Plus, in Zschiegner's image, you can search for a string of numbers. Type in your birthday: "81487" for Aug. 14, 1987 turns up an exact match among the 4 million numbers.

When asked why he believes society continues to be fascinated with Pi, Zschiegner responded, "For most of us: nostalgia. Pi is probably one of the few things we remember from trigonometry lessons in high school...But there are also great stories and mysteries associated with Pi. The number pops up in various ancient places, like the pyramids, or the temple of King Solomon...No pattern here, true randomness. How can you not want to draw a picture of this?"
