While mentoring a group of younger children at a local museum, the Power Coders recognize a chance to spread their programming knowledge to others. A medieval unicorn tapestry, coding skills, and a fascination with Minecraft come together in this inspiring and humorous narrative. The Power Coders and their young friends must complete a project about the unicorn. Naturally, the Power Coders decide to get coding. They guide the younger kids in understanding Minecraft mods and how to debug a program. This turns out to be the perfect way to encourage a reluctant girl who’s more interested in Minecraft than art or coding.
