+Realtime hide-and-seek application for the town of Fort Collins, built using
+[Phoenix](https://www.phoenixframework.org/) and [React](https://react.dev/).
+Group up with friends, designate a hider, and allow the rest of the group to
+find the hider in a city-wide search. Use various clues to narrow down the
+search space at the cost of potentially giving the hider means of thwarting the
+search.
