When there’s a disputed call in a pro football game, the ref heads to a canvas-covered monitor for a private screening of the replay. That hood, from Hoodman (800/818-3946,
), cuts glare from sunlight or the pale skin of shirtless fans. Hoodman also makes smaller models for cameras and laptops. The $40 E-2000 fits easily over iBooks or PowerBooks — perfect for Mac users who cart their laptops around the great outdoors or wish to privately watch their own videos.
