I'm Mr. MYTEK. Since 2014, I've taught kids and teens about technology through MYTEK LAB: coding, game design, robotics, and how computers work.
I also build the apps my students use. They're at mytekdev.com: make games, 3D designs, robots, music and simulations, right in a web browser with nothing to install.
Here I post short videos of things you can make with those apps, and whatever I'm building next. Every video links to a free try page, no account needed.
If you teach, many of the apps come with lesson plans you can use in class.
