You feed it a 4 bit number, and it connects the input line to a corresponding output line.

你给它一个 4 位数，它将输入线连接到相应的输出线。

And it started to output lines of code. I take those lines of code, put it into a TikZ compiler, and then I press enter. And then, boom, you know, the unicorn comes on onto the screen.

它开始输出代码行。我获取这些代码行，将其放入TikZ编译器中，然后按回车键。然后，轰，你知道，独角兽出现在屏幕上。
