mmm red power tubes running everywhere along side steam liquiducts and railcraft transport carts. Use a steves cart to navigate the base. hide all machines behind relays in the walls with RP2 iron cage lamps illuminating cozy forestry woodworked studies, dining rooms and workshops. Candles anywhere a lamp can't go, tallow candles for extra fun. Wear your goggles of revealing to fly in your traincraft zeppelin across a sky kept perpetually rainy by hidden forestry rainmakers.
My next build, most definitely this.
