I'm hankering over a subcutaneous neodymium magnet ATM, but I'm not aware of any UK bod-modders who offer it as service.
I have about 4 spare AGP graphics cards. Just in case, but of what I don't know.
what brand/models are they?
Mainly Radeons I believe. Acquired from old PCs at work that were due to be skipped.
They do actually have a purpose to some degree, my wife has an older Windows XP machine at work for use with a piece of specialised research kit that doesn't work under newer Windows. The PC that drives it had AGP graphics, so I collected a few spare cards. Four is admittedly excessive...
I like the practical uses that could lead to. My favourite is a magnet placed either side of the bridge of the nose for attaching a set of specs.
If they are strong enough, you could put several around your head for scissors, stapler and can opener, things I'm sick and tired of losing.
A walking stationary box.
I can see chefs using head magnets for small pans and keeping knives close to hand (so to speak) and surgeons for having lancets, scalpels and speculums ready to go whenever they are. :|
Don't think I have the cajones for that.
