# moonphase

![An image of the moon from moonphase.is](https://moonphase.is/image.svg)

This is a simple webapp that shows a textual and visual representation
of the current phase of the moon. moonphase.is displays a textual
representation and moonphase.is/image.svg returns a different image
depending on the current phase of the moon.

The webapp is hosted on Cloudflare Workers.
