From the developer:
Phiculator is a simple widget for your Mac OS X dashboard that calculates the corresponding value of a given number using the golden ratio. The application is useful to anyone wishing to create anything with divine proportions. You need to indicate which way you are performing the calculation, up or down the ratio, small to large or large to small.
