Huh, it might be interesting if the size of each participant's image could be controlled programmatically, e.g.

* The more you speak, the smaller your square gets

* The square varies in size based on the emotion in your voice

* Your square gets larger the longer you've had your hand up without being asked to speak

* The squares change size to equalize the size of everyone's face on the screen, eliminating the effect of camera and distance

(I wonder if Google Meet is hackable, as it's delivered in the browser rather than an app?)
