Over the last few years, I have served on a committee of the #NationalAcademies (chaired by @TammyKolda) to produce some posters and other related media to showcase twenty-first century #mathematics and its applications in the real world, suitable for display in classrooms or math departments. Our posters (together with some associated commentary, webinars on related topics, and even a whimsical "comic") are now available for download at https://nap.nationalacademies.org/resource/other/deps/illustrating-math/interactive/ .
