Four buttons that tell you whether the room is still with you.

People in the audience tap one of four things whenever they want: keeping up, thinking, losing focus, energized. You watch it move while you are talking.

That is a different feed from the polite faces in front of you, and it is the one worth having. Fifteen people quietly pressing "losing focus" during slide nine is information nobody was ever going to volunteer.

Questions, with the good ones rising

Anyone can put a question in, and the room votes the ones it wants answered to the top. You take the top three at the end instead of the three from whoever was quickest to raise a hand.

It also gives the people who were never going to put their hand up a way in.

On in thirty seconds

A code or a QR on your first slide. Nothing to install, nothing to explain, no accounts. People join while they are sitting down and it stays open for the whole session.

It is not a game

There is no score and nobody wins. It runs quietly alongside whatever you are actually doing, which is the point. Everything else in this library is the activity. This is the thing running underneath one.

Where it works

Training sessions and workshops, where the feedback loop is the job. Conference sessions with a Q&A slot that usually goes to whoever shouts. Internal meetings and all-hands. Lectures and seminars.

It is at its best in a room big enough that you cannot read faces, which is the room where you most need to know.

What it is not

An icebreaker or an energiser. Nobody is going to enjoy themselves because of this, they are going to be slightly more honest with you.
