Perlin Noise and Fibonacci Sequences
Perlin noise is an algorithm used to generate pseudo-random but mathematically predictable patterns. It is often used in VFX and games to create effects like natural terrain and textures like smoke and rough stone. It is much better than truly random sequences as the patterns created rise and fall predictably while still being pseudo-random. Pseudo-random sequences are not truly random and will always repeat eventually. Computers are incapable of creating truly random numbers, they will always be pseudo-random. Pseudo-random sequences require a 'seed' number that is multiplied and a sample of the same number of digits as the seed is taken for the next number.

The Fibonacci is a sequence of numbers where each number is the sum of the previous 2 numbers (e.g. 1,1,2,3,5,8). It is seen in many places, most prominently in art and nature. Natural objects like plants often follow Fibonacci numbers, and the 'Fibonacci spiral' is often used in art and design.
