Really cool concept!
I don't have much to add that others didn't already say.
I connected all the wires "backwards" at first, and was not sure why they weren't glowing. Turns out they have to be a specific direction, so I flipped them 180. Either the wires should work in both directions, or they should have a postitive/negative end labeled.
I also couldn't get the last light bulb to light, even though I flipped all of the wires into the correct positions.
All around, awesome job! The minimalist style really works well here.
