In full flow.

I was hosting an online event this morning.  The lower picture is a screencap from it.  The upper picture shows something of the setup.  Teams and Zoom are both good at replacing static background, but it gets dicier around the chair where sometimes the headrest appears as a weird appendage.  The green chromakey attachment helps with this.  Now I just look weird without unnecessary appendages.  

It's not a perfect system, but when hosting events I think it's better than a cluttered room in the background.

Still experimenting,
