I have a lot of artwork to do for this; several hundred sprites to draw, which I neither enjoy nor am particularly good at (I'd hire an artist, but I can't afford that).
So rather than continue procrastinating and occasionally doing a little, I'm poking at code again; added this little animation when things are placed. Also look at what's needed to get drag placement working (useful for conveyor belts).
