Luna Whale
Free art, math & science classroom — built for teachers
A teacher-parent asked me to build an art lesson website. Two years later, I couldn't stop. Now it has: • 180+ interactive art lessons • 100+ science simulations (chemistry, physics, biology) • Math games and geometry tools • Worksheet generators Everything is free. No sign-up needed for most tools. Built solo in Ho Chi Minh City, Vietnam. Honest question for educators: what actually gets used in a classroom vs. what just looks nice and collects dust?
What inspired this? Honestly — a single request from a teacher.
One of my art students' parents was an elementary school teacher. She asked if I could make a simple website for her art lessons. I said yes, thinking it'd take a week.
Two years later I have 180+ lessons and 100+ science simulations and I still haven't stopped. I'm an artist and game developer, not an engineer — so every tool took longer than it should have. But I kept going because teachers kept asking for more.
Everything is free. I'd love to know what educators actually find useful vs. what gets ignored. That feedback would help me decide where to spend the next two years 🐋
