To quote the section "Eggbox Phased Array":

> This unit cell, like an origami design, may be folded across either axis or laid flat, allowing you to physically change the direction of radiation. Because the phased array antenna on each face can steer the beam further, the antenna can be utilized to generate almost any radiation pattern using a combination of physical folding and electronic beam steering.

To me "physically change the direction of radiation" is rather explicit that the antenna isn't static.
