+Here's a silly thing I made while I was home sick today. It's a widget that
+produces a randomized pattern of [moves][rmoves] to scramble a 3×3 [Rubik's
+Cube][rcube].
+
+<figure class="figure--main-column figure--object">
+  {{< rubiks/scrambler >}}
+</figure>
+
+This thing is a [Web Component][wc]. The interactive logic lives inside a custom
+[HTMLElement][htmlelement], and the content and styling are specified inside a
+[`<template>`][template] element.
