I want to take Art of Invention 301: Applied Engineering, taught by Leonardo Da Vinci. He was so prolific in a variety of topics. It would be cool to see how he thought, and how to teach what he’s got locked away in his noggin.
I have a pair of green butterfly glasses we bought for a conference giveaway. Now and then, I will sneak them on when no one is looking and see how long it takes for someone to notice. It works great in Zoom meetings!
