Note : want a 360 of us? Just ask.
Exercise : use our photo and overlay a shape with a different color roughly front of each person. If you don't remember how to start a new project just use a previous exercise and clone it.
What are the advantages? Limitations? How can you use this?
Extra exercise : changing starting viewpoint on the 360, there are at least two ways to do it.
