Learners build
A collection of optical experiments that use color, pattern, spinning, and motion to create surprising visual effects.
Learners start by building different illusion-making tools, then test how speed, contrast, alignment, and pattern change what the eye perceives.
From there, they can redesign image pairs, spinning patterns, color blends, and repeatable experiments that make perception feel playful and hands-on.
Educator Resources
Student-facing slides introduce the concepts, guide the activity, and help learners reflect on what changed. Educator materials support setup, pacing, discussion, and extensions so this can work in classrooms, libraries, homeschool groups, clubs, or makerspaces.
