i think about being invisible a lot
thinking about uses tends to get sidetracked by thinking about mechanics—can you only turn your own body invisible? do you therefore need to run around naked everywhere? this would make any plans to steal anything rly weird; i think anyone viewing cctv of a suitcase full of money or w/e hovering around would figure you out, even if they couldn't believe their eyes
if you can make your clothing disappear too, what counts? could you hide a backpack? do you hide anything you touch? how big could it go? could you hide other people? would it take more effort to hide more clothing? would being invisible require a maintenance of concentration? would a failure of concentration just expose you to any onlookers, nude and all
you'd have to be so much more careful about crossing the road. frankly walking down the street could be hazardous

intelligence gathering
