PierreA, it was indeed inspirational. Partly because you're immensely talented. It's easy to make utilities with programming chops. But you made something so much more, you made an artistic, learning, _EXPERIENCE_. Kudos Pierre, your apps are super high quality and the colors are just blooming, very fun stuff, even for an adult like me to just mess around and watch the pretty colors fly around, or the ball physics. Cheers mate.

Thanks - it's just because I'm still a kid somehow, so I like it to be fun for kids like me ;-) For the UX, I worked in this field so I've got some experience/feeling/theoric knowledge in this field. Pedagogy knowledge comes from having homeschooled kids - you need to learn (and also you experience) how kids learn the best way.
