This is "real 3D".
You could move around the machine and see a different view.
I don't recall there being a limitation to the view.
Why couldn't they have advanced this technology to have 3D movies?
Time Traveler or Hologram Time Traveler is a stereographic laserdisc FMV arcade game released in 1991 by Sega and designed by Dragon's Lair creator Rick Dyer. It is called the "World's First Holographic Video Game" because it uses a special arcade cabinet that projects the game's characters. The holographic effect is an optical illusion using a huge curved mirror and a CRT television set.
