Recently, I was rather surprised to come across this video[0] in the gaming space, a tutorial for manually determining a videogame's intrinsic camera parameters using a common Computer Vision technique (although it wasn't referenced as such, which I'm assuming is to avoid intimidating the audience with technical jargon) The interactive tool demonstrated in the video was made using an online graphing calculator called Desmos[1], an interesting use case for something that was usually thought of as just for demonstrations.
