This is the Swiss German Version of the Speech Printing a bicycle, which I gave last Year at the Rhetoric Club Solothurn Meeting on Zoom on the 14th of December.
I used OBS with PowerPoint with a magenta background, so I could put the slides over the Camera Feed.
For the camera I used my iPhone with the obs.camera Plugin.
With the PowerPointToOBSSceneSwitcher from Scott Hanselman you could even synchronize the slides with OBS scenes.
