Someone’s probably already suggested this:
When Obi-Wan is wandering around the Death Star disabling the tractor beam, add a stack of rocks in front of him. It’s so he’s better concealed from the Imperials.
Hah. Have him force project them in front of himself. There one frame, rocks the next.
I want rocks in front of Luke as he’s watching the Sand People. The POV shot from his macrobinoculars just shows the rocks in front of him.
Just put rocks everywhere.
