MP3 Playing Floating Wave Machine
If you enjoy listening to tunes whilst soaking in the bath then this is the coolest way to do it. The JVC XA-AW33 MP3 player (catchy name) not only plays it also creates waves in time to the music.
The XA-Something-or-other has a capacity of 256 MB and floats between your knees at bath time. Along with the rippling waves it also produces a “soothing” light show, sort of like a disco in your bath.
The bath tub player is only available in Japan at the moment, thanks Random Good Stuff for the tip.
