This image below shows a tiling made from just two simple shapes, arranged in a pattern that never repeats. You can extend it as far as you like, and it will keep growing in complexity without ever falling into a regular cycle. That property alone makes it interesting, but the background is even better.

Here’s a short snippet that draws the Hilbert space-filling curve using a recursive approach.
It sounds counterintuitive. A curve normally has no area, it’s just a line. But a space-filling curve is a special type of curve that gets arbitrarily close to every point in a 2D square. If you keep refining it, the curve passes so densely through the space that it effectively covers the entire square. In the mathematical limit, it touches every point.

I’ve always wondered what was going on in president Bush’s mind right after he was informed about the 9/11 attack.
Using a technique called Eulerian Video Magnification we were able to estimate his heart rate, and compare it right before- and after learning about the attack.
