I love this idea, and I also love the way the website presents it.

Short blurb. Says what it is, how it's built. Then compares it to something you might already know about, to explain what it does. Lastly says why it matters, why it's cool, right before directly showing you the results in real-time.

Very nice. Very cool project. And I honestly find it impressive too how effectively and naturally it gets the point across.
