Today we can commemorate the 40th anniversary of the filming on the large rec room set, especially built for the third season of Star Trek.

Of course, the scene was never used and therefore we saw the rec room only in the abysmal "And the Children Shall Lead" and, slightly changed, in "Is There in Truth no Beauty".
I guess it is because of the "quality" of these shows, that I have yet to see any reverence shown to the design. While there are tons of renderings of the bridge, the transporter, the briefing room etc., no one - to my knowledge - has ever rendered the large rec room or even put him in the deck plans (I may be wrong there).
I think this is a shame and this setting has earned better. At least, it should get featured in a re-animation of "Time Trap" as the place for the reception. I can just about see the orion counsellor do a pole dance on those pillars.
Besides a small sketch in "The Art of Star Trek" there seems to be no source material other than the screen shots. But we are quite lucky: Although it was only shown so shortly, it is actually very well covered. I have arranged all available screen shots and we get to see the floor, the ceiling and about three quarters of all walls (the rest had probably been left open and would have to be extended).
Unfortunately, I don't have neither the tools, nor the expertise to recreate this location (I could add: "nor the time", but I am actually often amazed about how quickly some on this board can put something beautiful together with the neccessary know-how).
So I hope, somebody accepts the challenge to go where no Star Trek fan has gone before.
