The real magic happens when kids peek behind the curtain and understand how their creations came to life
"How did they make this? What exact words did they use?" Every Mini shows the conversation that created it.
Click "Show me the code" to see a README file and the actual HTML, CSS, and JavaScript. Perfect for curious minds who want to understand how it works.
"I love this calculator, but can mine be about dinosaurs instead?" Copy any Mini as a starting point for your own creation.
As kids expand their creativity, they're naturally forced to think more analytically about everything...
The Creative-Analytical Bridge: When kids want to build their dream spaceship game, they must break it down: "I need a moving ship, shooting lasers, enemy aliens, and a score counter."
Problem Decomposition: "Why doesn't my spaceship move smoothly? Let explain what I want it to do differently..." They learn to articulate problems clearly and iterate solutions.
Systems Thinking: "If I change this color, how does it affect the whole design? What if I want this animation on my homepage too?" They start seeing connections everywhere.
By the time they realize they're learning programming, they're already thinking like developers.
