Created by Paul Fryer last year, this "Chess Set for Tesla" takes 32 working vacuum tubes and turns them into chess pieces. Each tube slots into a port on the custom board, lighting up to show their identity via a glowing icon on the top.
The pieces range in size from 10cm to 15cm, while the board itself measures 48 by 50 cm and is 17cm deep. There's what looks to be a lid, which will hopefully prevent your cat from jumping up, knocking over the pieces and bending all the pins.
Seven copies of the set were produced, and presumably went on sale, but we doubt there are any left for purchase. Even if there had been, this beautiful game is unlikely to have been cheap.
