Somewhere in the southwestern United States, among the cacti, low shrubs, and shifting desert sands, there is a plain white box. In poor light and from a great distance, the box might look something like a phone booth. However, from close up, it is clear that the box is like nothing else on Earth. While it is only slightly narrower than one might expect, it is much taller, stretching to almost twice the height of a human being to accommodate the creatures who designed it. It is also completely blank and devoid of surface features. Credited to C.S.B.
