Shower technology is definitely an area that has been neglected over the years. Shower time is one of the best times of the day, so why not put bright minds to work developing products like this five-headed spinning shower head. It includes an outer, stationary ring that has 32 of the tiny shower spouts. On the inside the five head spin at 120 revolutions per minute that provide a massaging effect. It doesn't require any kind of electricity to operate (thankfully) and just needs a minimum of 0.5Pa to get the heads spinning. It is available from Hammacher Schlemmer for $100 and is probably worth every penny in looks alone, not to mention functionality.
