These are LEDs, but LEDs, when you shine light on them, they actually emit a little bit of energy on the lines, like a reverse solar panel, right? They're inefficient solar panel. But you can literally use them as eyes for this. So depending on what direction it's facing, one eye is gonna see more light than the other. That's where the light source is coming from.

And there's a really tiny brain in the middle. It's literally four logic gates. which is tiny. Your phone has millions of logic gates in it, right? Like a calculator. My cable has hundreds of thousands of logic gates. This thing, it's got four, okay?

What do you call it? A logic gate. So basically, all computing comes down to the concept of binary, on or off. Think of it like a light switch, right? It's on or off. You can do math with that. Let's go through it real quick, actually. We got three light switches, right? Yeah. Got to think which direction we're going here. So we got one on, two off. That can give us a one.

Turn them all off, that's a zero, right? Easy. Now we put two in the picture. You turn two on, you basically double the last one. So if two are on, that's going to be three, right? Basically, the first switch is the value of 1 or 0. The next one is 2 or 0. And then the next one will be 4 or 0. Next one is 8 or 0. That's binary math, right? Okay.

And all decision-making can kind of be based on this. So in this sense, it's very analog. But basically, this will eventually fill up and have enough energy charged that these four logic gates are suddenly making a decision. Like... This side's filled. Which eye is sensing the most light?

And at that point, it's gonna fire the opposing leg with all the energy it's gotten here to steer towards that. So you have this little bug-looking thing that walks, right? And it just constantly steers towards the light source. And to me, I thought that was really cool because A, it focuses on aesthetics, which is not super common.

And B, it uses really cool hardware hacks, like I said, with the lights here that normally it's for emitting light, but now you can reverse that and use it in an unintended way. And you can use really minimal logic
