The project begins with the drive to generate a feeling of lack of time. The final product has its place in meetings, and more specifically at the beginning of projects. Pulse is a tool to share and develop spontaneous ideas. Once it is switched on with a finger, it beats out the second for an unknown and non-configurable duration which is different every time. From now on, the only thing you know is : time is limited ! This lack of time will cause a speeding up, a state of stress and an obligation for each user to tell (or to write) their spontaneous ideas, without judgement or restrictions. So, this tool allows to broaden the research horizons of ideas and concepts.
