This work was done in close cooperation with Martin Yeh at Penn State/Brandywine and also supported by my small company.

Purpose
========

You put these videos up as a Virtual Background in Zoom. They act as timers for talks, classes, and meetings. 

To use them:

 1. Download what ones you want, or all of them.  
    Their names indicate how long they are.

    iccm-talk-timerV7-5minQ10-2fps.mov  
        is 5 min long with 10 min questions, at 2 frames per second

 2. You put them where zoom can find them. 
    I put them in a folder called Applications:Zoom-images on my Mac

 3. In the Zoom interface, in Settings, in choose Virtual Background, you click
    on the plus button, and choose the file to add.  

 4. Select the video as the virtual background by clicking on it. 

 5. Each time you click on it, it will restart from the beginning.  
    
    This is a feature and a limitation. You cannot add more time easily, and you
    cannot subtract time easily, you have to use another video to make that change. 
    For example, in a meeting, I set the timer for 15 using the 15 min video. I 
    was told we actually had 45 min, so I selected that video. 


Provenance
==========

These timers were developed for use at the International Conference on Cognitive Modeling (ICCM) when it was held at Penn State in 2016.  

They were revised for use in Zoom for Parents' weekend talks in 2020, and then expanded with encouragement from Peggy Stanton.  

There is no reason that we will not have additional timers for Christmas, Winter, and we will add a plain one in a nice formal font. The first public one is for Halloween. 

The top font is Advocate, a bespoke font by Butterick (https://practicaltypography.com/advocate.html), and the bottom font is Scary Halloween (https://phelanriessen.com/font/scary-halloween-font/) found in a library (https://www.dafont.com/).
