So that's the Microsoft Graph that includes presence APIs. So what's needed? We need an API to pull presence from and an API to push our chosen color to. The PresenceLight app is open source and up on Github by Isaac Levin and you can get it on the Windows Store free or in Chocolatey, WinGet, or download a nightly build. Here's what it looked like in the keynote:

If I'm not mirroring my pretense status, pull the accent color out and change the light.

Can we change room lighting to match the Windows Theme/Background accent color?.

I've been exploring 'busy lights' for over 10 years.

Red for busy, green for available, etc.Can we change room lighting to match Teams/Skype/Slack/Whatever presence status?.

Ya gotta mix it up! So I partnered with LIFX and Isaac Levin to accomplish two things: If you're going to watch something you for an extended time you'll need a little visual interest. We planned the whole thing out like a live stage play (I have a background in theatre) and one of the things that mattered to me was lighting.

During the Microsoft Build keynote last week - that you can watch free online here - we snuck in a LOT of detail and easter eggs.
