Algodoo

Again, no instructions! I am familiar with electronic components, but I have no idea how this scene works or what to do with it. Is it a game? Is it a quiz?

This is to be used to put electronic circuits together.
The lasers are the beam of electrons that move. If you shine a laser to a component, it would behave like in real life.
Plus more components are coming soon.

Oh, Okay. That's a great idea but for the average Algodoo user who knows little to nothing about electronic circuits, how would they understand how to build circuits with it without instructions? Along with detailed instructions it would be a great idea to show one or two examples of completed working circuits so that people have something to sort of guide them. Maybe show them what is possible with this scene. I'm sure that people would enjoy building circuits with your scene if they at least had some basic foundation to go by.

These are just my suggestions. You, of course don't have to do those things if you don't want to for some reason.
