faucet friend

the faucet friend is a device which slips onto a faucet to give a visual indication of the temperature of the water which is flowing from the tap. the above is a concept illustration although some functional prototypes have been designed. this is the kind of simple human-centered technology which i really appreciate. this might be the first time in years someone has made a useful technological augmentation to a faucet. bravo.
