That was a cool idea, and CHEAP.
I was there last night; they had three presentations at 8:30, 10:30 and 11:30. They projected the 363 foot Saturn rocket on the 555 foot Washington monument and during the taped presentations, showed it taking off, the capsule separation, landing on the moon, return to earth, etc. Had excerpts from JFK’s speech on getting to the moon by the end of the decade of the 1960s - probably his best speech. There were thousands there, burst into spontaneous applause several times, really wonderfully done for an amazing accomplishment. Extremely well done. They also had perhaps 20 tents where NASA and the Air and Space museums during the day had exhibits and live presentations.
