So you've lost your eyeglass case. Yes, again. Gets frustrating, doesn't it? Stop wasting time searching for stuff -- build a device that emits signals you can see and hear, so you can find what you're looking for instantly. Attach remote-control car receivers to any items you frequently misplace, and put the cars' transmitters in a control box that can activate the receivers' lights and sound signals. Then when one of the items goes missing, press the corresponding button on the box, and you'll have it back in no time. Or at least until the next time you need it.
