SinkPositive Accessory Sink: Fresh Water For Your Hands, Graywater For The Bowl

Every once in a while I stumble across a cool green gadget.  This is one I saw yesterday.  You just replace your toilet lid with this SinkPositive Accessory Lid, attach a hose to the refill valve in the tank, and presto: a sink on the back of your toilet.  You have fresh water to wash your hands and graywater for your bowl.

Something to think about!
