Even and odd numbers are randomly distributed in the decimal presentation of PI.
In my pictures the even numbers hanging down from the roof (=STALAKTIT).
Odd numbers grow up from the ground (=STALAGMIT).
One line represents 500 decimal digits, a complete picture represents 10 x 500 = 5.000 digits.
Let's walk thru our digital cave...
