The Holodeck

The holodeck is a very technologically-advanced room that is capable of creating visual and physical simulations. One can act out part of a story, movie, etc., or just change environments to various locations and atmospheric conditions. It uses three-dimensional holographic images to provide the visual feeling to it while shield generators make physical touch possible and atmospheric conditioning creates the general feel to the environment (it also has food replication technology for restaurant and eating environments). It is featured in Tiberius64'sstory If Summer Only Lasted One Day as something Phineas and Ferb make that Phineas and Isabella spend a romantic time in to catch up the day after they reveal their feelings for each other (the last day of summer vacation). This technological wonder is actually from Star Trek and is featured many times in various TV shows and movies of the franchise.
