What strikes me is 1) how sublimely simple the circuit in itself is comprised only of a 'terminal board, a 1k resistor, and some alligator clips'. Some third party hardware helps just a bit. But 2) this doesn't even rate news here, and I am not suggesting it should; and 3) the story does not mention Pittsburgh's long long history of putting random devices on the Internet.
On point 3... one could argue Pittsburgh has a big part in the history of gadgetry on the web. Here is the seminal history of CMU's Coke Machine on the pre-web Internet. Finger that.
