I'm trying to create a kiosk mode for Raspberry Pi, but I also want to be able to display a countdown (near the bottom) to a specific time like 9:00am and show itself like 0:00 or 00:00 respectively. The countdown needs to be independent of when the images change.
What is the best way to do this? Is there a viewer that already has this type of option?
I'm currently using feh which works for displaying the images, but has no way of showing the countdown. It would also be really nice to have the countdown automatically start and stop at different times, but I can work on that after I find a way to get it to show.
