For today's Advent Calendar, I'm sharing a colorful wallpaper I made for my phone using Racket. There's nothing too deep about it, just a bit of fun, but it does demonstrate a simple way to create a nice rainbow color gradient. It illustrates the power of Racket's `for/fold` form as well as using the `pict` library to create images. The wallpaper and the code is available at [https://github.com/zamora/wallpaper](https://github.com/zamora/wallpaper)
