Heh, story straight out of the Strugatsy Brother's "Roadside Picnic" right there: Advanced tech (I was going to put quotes around it, but it really is) created by a defunct civilization found by people who see side-effects, but don't understand the functionality at all. This is like those island tribesmen imitating air controller hand signals, because they thought it was magic that summoned supply planes.
