HMF a website that watched my every move

One time during school I stumbled across a website, if im not mistaken i got there from the website “The Useless Web” (like 70% sure might be wrong tho) and it took me to this website that had a white screen, and a the top it would type in black letters exactly what I did. For example I was in class, and it described my features “The girl has ___ colored hair and a confused expression” then when i waved “Your waving” etc. There was nothing else on the screen but the text. It would just type out exactly what you did through the camera automatically. It was super weird and scared me and now that years have passed I’ve tried finding it again just to never hear about it. Ive looked it up, i cant seem to find anybody talking about this or find the original website.
