You found one.

That little dark figure you spotted is La Espera. It means "the wait." It stands where people in LA stand around waiting: train platforms, bus stops, that corner where the bus was supposed to show up ten minutes ago. The one glowing pixel is the color of the metro line that serves that spot. Or should.

Every figure is 3D printed and held up with magnets. It doesn't damage anything. It's just asking a question: why doesn't the biggest county in the country have a metro that's safe, fast, and reliable enough that you'd actually pick it over driving?
