I came across OpenCV modules that allow controlling your computer mouse pointer with your finger in space using open-source computer vision software and a webcam. I slightly modified the source code to

I had a crazy idea of creating a “video game” using the Raspberry Pi 4 and a cool machine learning algorithm working on the backend. Happens that the idea was too big to execute fast and I got a bit frustrated
