It's a kitchen timer, as you might use in a kitchen. Twisting the top half winds the mechanism to the desired time, and it ticks away until the mark reaches zero and a bell is rung. A common kitchen timer.

What sets the Louvre Timer apart is that underneath its clear plastic exterior are a series of coloured stripes that can overlap each other. They are connected to the ticking mechanism in such a way that if the bell has not yet rung, the whole timer appears green; post-ringing, the timer appears red.

The overall effect is that a multitasking cook can, at a glance and from some considerable distance, ascertain if the timer has yet rung or not.

Mrs. Maxwell Buchanan has something similar. It's a saucepan from which smoke billows when a critical time has been exceeded.

Personally I'd be happier with less.

I live to amuse. At least that was the verdict at my last career review.

Stoves should come equipped with overhead smoke alarms which turn off the stove.

I think the time should be indicated by the number of moiré stripes (apropos of which, I'd like to see a reworked version of the musical "Oliver!" in which the eponymous orphan hero asks "Please sir, may I have some moiré?")

I really like this idea, and believe it should be baked.
