Lego has been around for donkeys years. Each month I come across something different built out of Lego. This month we have already had the Lego iPhone (completely bricked) and now we have the Lego Mindstorms NXT automatic toilet flusher. It is named RoboFlush and has one purpose. That purpose is to automatically flush so that you do not forget. It works by using an ultrasonic sensor that sits on the top of the toilet and when it detects movement away from it, it will then flush.
