“And the dimensions have the precise ratio of 1:4:9. “

From “2001: A Space Odyssey.” 1 squaredx2squaredx3 squared. And with a fourth dimension of 16, I would think.
In the movie, "2001; A Space Odyssey," the obelisks, no matter their size, have the ratio 1:4:9.
The (underlying) image at left is an extremely high resolution example of what is believed to be Extra-Terrestrial-generated software (note the ratchets that are similar to the crop circle at right, where π is represented to 10 digits). Prior to this example (at right) from 2008, using such a ratchet system was not known ever to be used to represent a number (without digits as we know them).
