This is a VFX test I did where I wanted to create an infinite shopping aisle using nothing but a single clip. I did this in Nuke and used a both 2D and 3D tracking, a lot of projection mapping & roto-paint, and other smaller effects to achieve this look. It is absolutely not perfect, and I'm well aware that the track slips a bit, but as a quick test filmed on my phone and edited in a day, I'm rather happy with the outcome.
Here is a quick breakdown showing a before and after of the shot.
