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?
