There was a time when I could'nt sleep without my radio on, but as you age, I guess you become more sensitive to lights and sounds. Nevertheless, designer Kaffee Matthews developed the Sonic Bed with built-in speakers so you can "feel the music". The bed is a social experiment exploring our perception of sound. It has specially constructed pieces moving up and down your body, as well as 12 sounds playing independently at any time. Hmm, I wonder if you can plug-in an iPod?
