The 6120B Hybrid was too big to bring to Las Vegas to show off. (It shows up on Google Maps though...)
Here's a video somebody shot at the show with a 3D model of the machine.
This thing is big - like 4-story building big.
I worked on a video on it, but I can't find that video. I think it's something that they used at their trade-show booth for the product launch, but hasn't been posted to YouTube or elsewhere.
