After reading
mcc's node,
Usage of the Sony Playstation 2 controller as a back massage device I thought top
idea! Luckily for me soon after reading mcc's node, I read the node
Vibrator Warning.
Inspired by this
node I flipped through the user's
manual for the
Sony Playstation 2 Dual Shock 2tm controller, and made the startling
discovery of this
warning:
Safety Issues (Vibration Function)

These ailments may become worse due to the vibration function on the controller.

I know most of that has nothing to do with mcc's node (I put italics on the related part), but I thought I'd post the whole thing for other people's safety because I don't think most people would read the manual.
Anyway, sorry mcc, but as the story of Vibrator Warning taught me, don't use devices not intended for massaging as massage devices as they usually have a warning telling you not to.
