the video i am referring to was just one guy sitting at a desk holding a single fiber cable in his hand and projecting some image onto the wall and desk and whatever he pointed it at..

i've seen that mit video in the search results but the description: "The image of printed words is transmitted through a bundle of approximately 25,000 coherent optical fibers and projected onto a screen"; states more than one fiber

the actual video itself aside i just wonder if there is any information on image projection through a single fiber

Nah, image through a single fiber sounds like a hoax, it's against the physics of how optic fibers work. But if it's a bundle on fibers, I can see how that would work, but again, projecting it onto a surface seems unlikely. The moment the light leaves the fiber, it starts dispersing.
