That's a lot of pen is ?

pretty... but i'm not sure if this works long-term. all that metal may have some unexpected thermal side-effects in winter and summer, making for chilled or superheated feet.

also, if that's polyurethane or similar, he's just deep-coated all those floors with carcinogens. good luck with that, buddy.

Holy fuck that's dangerous... Better hope his wiring never, never has any kind of problem. That and good luck getting your Wi-Fi to work sucker.
