One of the most spectacular collaborations unveiled at Brickworld 2013 was a cyberpunk city full of tall buildings lit up with working lights. I had the privilege of providing a bit of input on the Japanese signage (a lot of which is very, very silly), and I was overjoyed by how wonderful the end result was.
It’s beautiful in the dark, but you can see a lot more of the detail in the light.
Some of the signage is built from EL (electroluminescent) wire, though there’s plenty of brick-built lettering too. Carter saved my personal favorite for himself — a big building in the background that says “Foreign Girls” in giant red letters.
