Thanks to the brighter colors on the display poster, much more of the detail could be made out, confirming that this indeed is the same CG model seen on the bonbori festival lamp. As for the “sticks” holding up the hull as if it were a model kit, the brighter version revealed that they aren’t sticks at all. Instead, they appear to be power cables hanging from the hull. The ship is hovering rather than resting.
