In this blog, I have written quite a number of articles about prime numbers. In one of my posts, I have emphasized that geometrically, the dots that represent a prime number can only be arranged in a 1 x *p* rectangular arrangement where *p* is prime. Composite numbers on the other hand, can be arranged geometrically into more than 1 rectangular arrangements.

Stephen Von Worley has given a more beautiful *definition* of primes and composites in his Factor Dance Animation . The brilliant animation is a rearrangement of dots (circles) that represent numbers into different groups every second. Its aim is to show the “compositeness” and “primeness” of numbers from 1 up to 10,000. Worley’s program used the algorithm Brent Yorgey, the writer of **The Mathematics Less Traveled**.

You can read more about the animation at Wolrey’s post titled Dance, Factors, Dance. You may also want to watch the beautiful animation.
