So what is it?

Magic Keyboard is a playful web toy that makes your keyboard do something visually fun: every key you press spawns a colorful letter that drops, bounces, and tumbles around the screen like a physical object. It's the kind of thing you open in your browser, mash a few keys, and watch letters cascade with satisfying physics. The project was inspired by an animated GIF the creator spotted on Reddit. It recreates and expands on that idea as an interactive web page you can try yourself at magickeyboard.io. You just load the page, start typing, and watch the letters fall and collide in real time. Under the hood, it's a lightweight JavaScript project that combines a couple of tools. One bundles the JavaScript code so it runs in the browser, and the other is a physics engine that handles the realistic movement, gravity, bouncing, and collisions between the letter shapes. The README doesn't go into much more technical detail than that. This is a novelty project, not a productivity tool. It's for anyone who wants a moment of amusement, maybe a developer looking for a quick break, or someone wanting to show off a fun browser experiment to friends. The creator also notes that the original author of the inspiring GIF reached out to share the backstory, which is a nice touch. The code is open source under the MIT license, and the creator welcomes pull requests, so anyone interested in tweaking the effect or adding features could jump in.

Copy-paste prompts

Prompt 1
I want to recreate a fun web toy where pressing any key drops a colorful letter that bounces with physics. How should I structure a lightweight JavaScript project with a bundler and a 2D physics engine?
Prompt 2
Help me add a new visual effect to magickeyboard.io, like confetti explosions or changing letter colors based on key position.
Prompt 3
How do I bundle a vanilla JavaScript project using Browserify so it runs in the browser with a physics engine like matter.js or planck.js?
