This is a great idea to describe red stone to noobs. I think we should display basic concepts and get harder and harder, and maybe machines that are just for fun (piston holes, door opener, etc), but NO auto farms. So maybe the first thing you do is explain the purpose of the items then put them in application and start making basic machines (bud switches, block updators, etc) and then get to the for fun builds (doors, traps, etc).
I love the idea, but I think our first priority is getting the down worlds back *cough*skyblock*cough*
