Using internal and external reflection elements in one-, two-, and three-dimensional space, the concept of chirality can be introduced in simple terms that are readily understood. Illustrations of 2-D chirality include block letters of the alphabet and the popular video game Tetris. The concepts of 3-D chirality follow logically and can be simplified by projection back to 2-D. Several examples are given, and a PowerPoint presentation of the concepts is available in the Supplemental Material.
