This project is conceived in four parts. There are two light arrays that function as binary counters, and there are two audio tracks that cycle on and off. The larger light array contains twenty-five lights and counts at a pace that will allow it to cycle through all of its available combinations once every 365.25 days (one trip of the earth around the sun).

A brief explanation... This three part machine, controlled by the period of the swinging pendula, searches for prime numbers. When it finds a prime number, it prints it. When it does not find a prime, it prints a space. As each of the three modules finds primes, it keeps a tabulation of the total quantity of primes found.
