Nina's Little Universe is a handmade, interactive science world I built for my five year old daughter. Children spin Earth to discover day and night, explore Moon phases and eclipses, experiment with light, and meet planets through touch-driven missions. It's bilingual in English and Albanian, free, and requires no account. What began as a personal project for Nina is now being used in schools, helping children learn by touching, testing, and discovering instead of passively watching.

GPT-6 Astra Challenge

How did Astra change the scope or ambition of what you built?

I started with “help me explain Moon phases to my daughter.” Astra helped turn that into “what if she could explore them herself?” The scope grew from a simple explanation into a whole cardboard-style universe with spinning planets, day-and-night missions, Moon phases and eclipses. It made trying ideas fast enough that I could follow my curiosity instead of cutting everything down to the smallest demo. The biggest shift was going from something I could show Nina to something she could play with—and now something I’m sharing with other families and teachers.

Hey Product Hunt! I'm Ari, Nina's dad 👋 This started with a simple question: how do I explain Moon phases to my daughter without losing her halfway through? So I built her a little universe. Nina's Little Universe lets kids turn Earth, follow their home into daylight, explore the Moon, and play with eclipses. I wanted it to feel like a cardboard world we could have made together at the kitchen table. I shared an early version on X, and it received over 52,000 impressions and 6,000 link clicks. It's free to explore. If you are a parent or teacher, try the first day and night mission with a child and tell me: • Where did they get stuck? • What could they explain in their own words afterward? And what space question has a child asked you that sent you straight to Google? This started as something personal for Nina, but I realized many curious little minds learn better by doing than by listening.
