I had to put this "temporary" Google Slides show here because my laptop doesn't have powerpoint and I was doing a presentation today at an art center. Unless you know how to "enlarge" this to full screen it looks pretty bad. The "full screen" icon is in the lower left... looks like four arrows pointing in different directions... or you can hit Ctrl+Shift+F... there's also a slider bar so you can center it if you don't want to make it full screen.
I do plan to turn this into a YouTube video when time allows so it doesn't bleed into the right hand menu. :-)
