== [[Real Life]] ==
* The field of [[wikipedia:Archaeoacoustics|Archaeoacoustics]] opened up the possibility of a variation on this idea, that under some circumstances it might be possible for pottery thrown on a wheel to accidentally encode, in the manner of an old Edison cylinder or vinyl LP, nearby sounds.  Around the middle of the '00s, [http://www.ohgizmo.com/2006/02/20/5000-year-old-recordings-caught-on-pottery/ the idea caught the public imagination] and started showing up everywhere.  Sadly, the [[Myth Busters]] [[wikipedia:MythBusters_(2006_season)#Pottery_Record_.28Archaeoacoustics.29|showed]] that only the most general of acoustic phenomena could get so encoded.
