Phi, the Fibonacci sequence, the golden ratio, the golden section, the golden mean, the divine proportion. It’s known as many things, but the ratio they all refer to is the same, 1 : 1.61803399... Found in art, architecture, design, and most intriguingly, in nature, this ratio has been used throughout history and today for its aesthetic beauty. Phiculator (pronounced "fye·cu·la·tor") is a simple tool which, given any number, will calculate the corresponding number according to the golden ratio. Useful to anyone wishing to create anything with divine proportions!
