Millennial engineering:
The whole wide stance legs and retro rocket thing takes up too much space and adds complexity.
Should just go with a parachute.
Seriously, I was always fascinated by the multi-faceted shape of the lunar lander. Not the usual way to make a pressure vessel, but I guess it only adds the volume you need. All the artist conceptions before and since (see the article) have been simple shapes like cylinders or spheres.
Particularly wild is the standing position of the landing pilot, with his large window looking down on the lunar surface. The engineers at Grumman were certainly thinking outside the box. To think of all these situations where no one had been before, and come up with solutions that worked is a testament to their skill.
