Theme 100% locked in - the game layout is actually designed to work with the theme as that was fixed from the outset. But we're keeping the theme under wraps until it's done. We'll probably get some progress over winter, small bits happening in the meantime, ie nug's built the high voltage ps which is a simple and rather clever use of a 110 to 24 v us transformer - 230 local in give a nice 48 v for the solenoids.
