Nice video

I clicked on this vid because it's a tool I have never seen before. In the video we can see a bit of how it works. However, I don't understand fully what it is for. Why is it important to have such a tool? How is it important?

A poorly described video unfortunately,, came to see how these tools are used and applied, came away with more questions than answers...
