WTF is this?

The images you see on this blog are output from various Ulam spiral generators I built in Flash, Python and most recently using Arduino. Generally, each dot in an image represents a number with integer 1 at center. In addition to writing algorithms to test each number for primality within a set I have discovered that an infinite number of calculations can be performed to create new designs and animation algorithms. The simplicity and speed of these algorithms make them an ideal fit for embedded systems graphics, scientific, mathematical and artistic explorations.

Prime Numbers Ending in 1

A Ulam spiral with only primes ending with the integer 1. We start off 1, 11, 31, 41, 61, 71, 101, 131, 151.....10,331!


This prime goes to 11. Here we have all primes ending with the digits 11 from 11 to 12011.
