Some time ago, I came across a fascinating demonstration (likely on HN) that involved two clear plastic sheets, each printed with a random distribution of points. When overlaid, the density of points varied in certain areas, revealing a distinct shape.

I've been unable to locate the original demo. Here, I decided to create my own version.

While the website is mobile-friendly, I recommend viewing it on a desktop for the best experience. Also, don't forget to click on 'BIN OCULAR' at the top of the page for a little surprise. Enjoy!
