I don't know why this challenge made me think of the Fibonacci sequence and the golden rectangle. I guess betweed kind of reminds me of the top of a conch.
I have a massive obsession with the Fibonacci sequence. While I'm not the best at math and have entirely given up on remembering numbers (phone, codes, any kind of sequence...), the Fibonacci sequence is truly intriguing. If you don't know it,
1, 1, 2, 3, 5, 8, 13, 21, 34, and so on.
Basically the first two numbers add up to the next number. It's know in the math world as the Greek letter phi, Φ, or the ratio 1.618.
It's used in art, found in nature and proves that Johnny Depp is hot.
Somehow, our eyes are naturally drawn to objects, people, whatever, that most closely follow this ratio. It is the best way for plant leaves to grow in order for them to get the maximum amount of sunlight. It's the best way for sunflower seeds to grow to pack the most of them into that area as possible. It has been used by many of the greatest artists.
It's, in a nutshell, super cool.
