This is so brilliantly simple.

I semi-regularly chair or panels and very often the venue hasn’t thought about a countdown timer so that I and the speakers know how long we have left. Having a timer massively improves the quality of a panel from an audience perspective as you can better pace things, move speakers on, wrap up without rushing, and so on.

Because of how often a timer wasn’t available last year I made something where I could quickly spin one up using ffmpeg. This is much easier and much more useful. (And doesn’t require having my Mac with me!)

Being able to stick one of these on an iPad on a table so that speakers can see it but audience can’t will be really useful.

Thank you!
