What does virtual reality look like? Anything you want. a Concert space, a waltz thrugh history, a fall through fractal amthermatics. What virtual reality is used for is the same as any other medium of “media”. It is the communication of ideas, with the intent of provoking thought, and propogating notions.
Literally though, virtual reality looks like a video game because virtual reality worlds are built in game engine software. These are visual development tools to manage art and technology, to create virtual worlds with environments, characters, rules and an objective. Virtual reality can also be pointless one could suppose, just as much as life can. It is up to you to create something of it, if you wish.
