I teach how to build a fun little project, blindfolded. It's inspired by @Vsauce's video on the Bezold effect: youtube.com/shorts/3Yqu30QHkro
I do it because things didn't go that well in the previous one: youtube.com/live/nuuHeNgZDEY
And I kind of need this blindfolded thing to work for a conference.

In Lesson 11 of the Understanding AI course, Im thrilled to unveil the magic of 3D extrusions in JavaScript. Today, Ill guide you through the process of making elements pop up in the third dimension, a technique commonly known as extrusion. And when I say everything, I mean it – from buildings and cars to road borders.
But heres where it gets really exciting! Ill demonstrate how to move the camera behind our car, allowing us to see it in action, and share a trick often used in racing games to enhance the feeling of speed. Get ready for an eye-opening experience as I expose you to some really cool techniques that will elevate your game development skills.
Join me in this lesson where we explore 3D extrusions and dynamic camera movement in JavaScript, unlocking a new dimension in your self-driving car project. Like, share, and subscribe for more lessons on AI, game development, and cutting-edge programming concepts!

Welcome to the course where we build a self-driving car simulation in a virtual world using HTML, CSS and JavaScript. The world editor we built is nice. Feels really fast to use, definitely minimizing the number of clicks. But you know what’s better than a few clicks?
⭐NO CLICKS!⭐
Lets learn about OpenStreetMap: how to query data from it using overpass turbo and how to parse it in our code. You’ll also learn about real-world coordinates, how they work and the geometry of our 3D world. 🌎
Have Fun! :-)
