Attach the sonic nail finder onto the center of the back of any
picture, clock, or "purely decorative" torture device that you
are
trying to hang. Using wavy-handy-electromagnetic spacial
theremin type technology in a small chip and CR2025 battery,
the
small piezo speaker in it produces
the highest pitch when the
nail
is directly above it, thus allowing you to hang said picture on
its
hook with ease.

If the wall fixing had a small amount of a gamma-emitting nuclide like Cobalt-60 or Strontium-90 embedded* in it, then a piece of radioflourescent plastic applied to the front of the item to be hung would show a visible glowing spot as it moved over the fixing; the radiation will penetrate the material and give you an exact positioning cue, in X, Y and Z axes. |

*You can't make the whole thing from them, as those metals have unsuitable mechanical properties. |

"a small amount of Cobalt-60 or Strontium-90 ..."

How about if the head of the hammer is contains a
*barely* sub-critical amount of something like californium-252,
and the nail-head insert was *just* the right extra amount...?
Once you've nailed the fastener in, you won't need to
hang anything else. Problem solved. |

But in all seriousness - use a typical steel hanger. Glue a tiny
rare-earth magnet on the back of your objet d'art where you
think it needs to be as your "locator." It'll give a little tug
when you've positioned it correctly. |

In bulk these things cost pennies a piece. I have a lot of
them around the house and constantly find new applications
for them. |

[kdf], you need to get out more and meet other humans. |

Coming from us, that advice should worry you. Lots. |

Hey, I'm not the one who suggested a Theremin-gy picture
hanger... go pick on Ray. |
|

That's no fun, he's more deserving of pity than condemnation. The whole idea has a flavour of Scott Adams' "Engineers Explained" about it ... he actually mentions picture-hanging. <link> |

Oh, all right. But I'm still disappointed that you didn't remark
on the sub-critical nuclear hammer idea... |
|
| |
Aw, we did that three Saturnalias ago, with the Intercalary's novelty nutcracker. Oh, how we laughed ... |
|

Pictures or it never happened. |

I have rare-earth magnets holding up a piece of finish trim
wood on my basement ceiling. As the area was in front of a
crawl window and hiding water pipes, a gas line, a cable or
two, and the Case-Western ARPAnet trunk line, removable
access was important. |

Murphy's law, it will find that nail/screw that missed and was plastered over without removal. |
