Having had a number of experiences with roommates that who have the tendency to fall asleep in the shower, I humbly present a solution.
This shower head functions as the method to turn the shower on and off, a physical display of the amount of the time that you have been showering and a way of waking up those who might begin to doze in the comforting warmth of a good shower. If untouched, the shower head slowly descends and eventually shuts itself off - either prompting the user to wake up and start their day (again) or restart the shower to continue cleansing himself. For those without the tendency to fall asleep in the shower, this functions to remind the user of excessive water usage and waste.
