PEARL
LED traffic light set of 4

Use a traffic light as a mood barometer on your desk.

When the mood is relaxed, you switch to green; on stressful days, your traffic light is set to red.

The signal generator shows your colleagues what the situation is like and thus helps to avoid disruptive exchanges of words.

Just like in real traffic, the traffic light should also defuse critical situations at your desk. super funny and practical at the same time!
