I just remembered one interesting thing, which may or may not be important.
The 16mm DAC (Data Acquisition Camera) was mounted in the right observation window, pointing down towards the area in front of the porch. Before exiting the LM, Dr. Aldrin set it to take time-lapse shots at a rate of one photo per second. It captured the whole procedure while the astronauts were setting up the flag, posing for photos, walking around doing experimentation work, etc etc.
What's interesting about this footage is this:
1) Once the flag had been set up, it stays absolutely stock still, without even so much as a hint of movement. And that's a nylon flag, flimsy as anything you please.
2) If you watch the footage speeded up, the shadows are moving. I'm not sure if anyone has measured their motion and compared it with the moon's rotation wrt the Sun, but the whole EVA lasted two and a half hours, and the movement is only about a degree. Doesn't look like they're in Kansas...
