This clever mug automatically displays “OFF” when it is empty and ‘ON” when it is filled with coffee or tea. It is covered with a heat sensitive pigment which allows it to change from black to white or vice versa depending on whether it is filled or not.

I love that but I’m a sucker for type on a coffee mug.

I think it would be better if it said full/empty, or hot/cold. Cool idea, and definitely classier than the ones where the lady strips as the cup gets hotter.

J’adore votre blog, il est vraiment fun(sorry, next time in english)

Simon: the on/off joke isn’t applicatble to the cup itself, but to the drinker of its delicious contents!

Thank God the type is not in comic sans or arial!
