Unique environment

My idea for this project is the classic Sci Fi idea of time travel with my own personal twist. This project will consist of multiple worlds or places in time in which the user can exit the time machine and explore  the surrounding area and the people animals and things that make said point in time unique (no set number of worlds yet but probably around 8 or 10 at this point).  The time machine will consit of multiple button indicating each time that the user can travel to, above that will be a large glass widow showing the world that the user is presently in and lastly above that is a clock with the exact date that the user is in. To the right of this will be a door the when clicked on will allow the user to exit the machine and step in said world to interact with everything present at that time.  Personally when leaving a time i want something to attack the time machine just before the person escapes to a new time like in  every cliché time travel movie ( an example of this would be a t-rex just about to destroy the time machine and right before it get to warp into a new time)

Who live there?
you, since i want this to be a first person experience and depending on the time an place the people and things historically accurate to said time

Where am i going to get my imagery from?
a lot of different places but my main idea is to get historically accurate paintings, photographs and drawings and make each world into a big collage of multiple images.

How big will my interface be?
full screen

Why would your audience want to interact with your environment?

who doesn't want to travel through time and explore places they could only dream about?
