In high school I took electronics and learned enough about capacitors, inductors and transistors to design and test simple circuits. I'd gotten a Radio Shack "100-in-1" kit when I was in fifth grade, but the projects within were all opaque recipes to me. Most circuits had illustrations with cartoons components saying things like "I'm the capacitor, and I give a little 'kick' to the transistor!". I remember being kind of surprised at just how un-enlightening these cartoons were. If I followed the wiring steps for a project and then it didn't work, I'd double-check my wiring. If it still didn't work, there was nothing further to do; I just gave up. I had no idea how it 'ought' to work, so there was nothing I could measure or verify that would mean anything to me.

This is what I wish I'd had at the time. I'd have understood intuitively what each of the components did. The time-scale is slowed down enough that I could see what was going on. I could build and test in stages and see how each new change affects the outcome. Endless experimentation and possibilities...

This is just terrific!
