Ever wanted to make someone's head disappear? Just stare at them and concentrate. Turn 'em into swiss cheese. This can be done to any substance. You can control the hole's size, but its maximum diameter can only be as big as the distance you are from the object, and its maximum depth is half that distance. You can unmake a hole by staring at it again, so you can pass through walls and stop followers. This can be used for spying, though it is not as discreet as X-Ray Vision.
