Very cool!
However, I have a dumb question (as someone who doesn't know about electronics): how is it different from a YouTube lecture where the same content is demonstrated with real objects or with animation?
I'm not sure if the interactivity in these examples add much value to learning, as the buttons only serve as 'show me the next animation'.
If the eventual goal is to build a virtual sandbox that models the real world more closely, then I think this is a great first step and a great idea!
