The mass gets thinner as it gets longer, heading north. The first few cubes reach the opening and the outer line of traveling cubes shift motion 90 degrees and start entering the tube. After enough cubes have entered the tube to anchor a hoist of the remaining mass, gripper cubes grab individual I-beams and haul them to the top, then rotate the beams to enter the tube head first and disappear. After the last beam, the remaining cubes are hoisted by cubes at the top, and the whole mass disappears from the first aquarium. In the second aquarium, a group appears from the tube descending down the glass in a line to form an elevator for the mass.
Beams appear and rotate, then descend to a forming base of cubes.
Once all the cubes are out and down, the mass begins reassembling the box, starting from the ground up. After the box of beams is complete, the cubes retreat to the center and again, form a pyramid. This process can be repeated until the batteries drain, or indefinitely if supplied with recharging induction coils in the floor of the aquarium. This is Robotic Construction International's first commercial application of Fractal Robotic technology. Emergency aircraft runways could be erected by programming these robotic cubes to arrange themselves in flat masses of plates.
