Paul Priestman has designed a water saving gadget for your shower called the Waterpebble. The Waterpebble monitors the water going down the shower drain and alerts you of your water usage (like a stop light) with green, yellow, and red lights.

is it me, or did this take like a minute + to calibrate WITH the water running (um, a waste)… then 10 seconds (ish) to tell you you’re wasting water.
So, does that mean you get 10 seconds to take a shower (unless you trick it for a bonus minute during the calibration time)?
