I love ‘invisible’ magnetic surfaces. I have a few around my apartment – some that I’ve installed, some where I’ve found ferrous metal studs behind the walls (I live in a wood-frame house, so they’re not too common). And this project by Steve Hoefer is a great use of magnetic hard drive parts, to create those ‘invisible’ holders – the exposed magnet look is pretty swanky too!
Keyholders are pretty utilitarian, so they’re a common target for designers who want to add a bit of flair. And magnets have a bit of natural magic about them. Since keychains usually have at least a bit of ferromagnetic metal in them, magnetic keyholders are common and plentiful. And since grabbing the keys and turning off the lights often happen at the same moment, putting your keys on a light switch plate is a natural pairing.
