CrystalClass

Interactive 3D crystal structures for chemistry classrooms

CrystalClass is a browser-based tool that lets students and teachers explore unit cells in interactive 3D. Built for high school and introductory college chemistry, it replaces static textbook diagrams with explorable models — FCC, BCC, NaCl, diamond, and more. Features include guided learning paths, coordination number calculators, packing efficiency visualizers, and a teacher toolkit for classroom demos. Works on any device, zero setup required.
