You're joking, but my wife got us a box emitting bird sounds when the motion sensor is triggered. Suffice to say that it does absolutely nothing to mask the sounds that are produced on a toilet, it's just another ridiculous layer on top of it.

Sounds pretty relaxing for the user, though!

Right, one might suppose so. Alas, the chirps echoing within a tiled 3x3' cell grind my ears. Besides it feels a bit out of place within these plain white confinements. I just can't conjure up the mental image of being out in the woods.

But you have to pick your battles with your partner. I'm turning the volume down, and when the battery's empty I don't exactly hasten to change it.
