In a recent episode of Community, Abed and Troy showed Annie their
“Dreamatorium”, which looks identical to STTNG’s holodeck.
Abed later notes the Dreamatorium can turn into a courtroom in “the
blink of an eye” and then snaps his fingers.
This is reminiscent of STTNG’s first episode (Encounter At Farpoint),
where Q turns the bridge into a courtroom instantly, w/ a dramatic snap
of his fingers.
