Thanks for this! So looks like he's getting somewhat of a start on a few features like Redstone then. Looks like we're one step closer to doors, which I hope we get because all my houses are missing doors and it just looks wrong.
I had no idea the black lamps were turned off white lamps! Anyways a black block has been necessary for a while now especially for pixel art.
Also, only white lamps can be turned off? That's very odd.
Hopefully in the future, this doesn't mean that lamps require a power source, it would suck if they did especially now considering that we've been placing loads of lamp slabs and lamp blocks everywhere. Perhaps redstone-like lamps should be their own thing.
Maybe you could have lamps that require power, and through some advanced wiring system, you could control what colour they emit, allowing for advanced ingame displays or something.
Perhaps Redstone in Cosmic Reach could go above binary and wires could carry different types of data, unlike Redstone.
