I have been working on a personal project for about 3 weeks now. You can go to anywhere using Street View and change a year which will then show what that place might have looked like in that year. Kind of like you traveled time to that place.

You can then generate a video, chat with a tour guide and generate a 3d world and even walk using VR (my personal favorite feature).

And here are some of my personal favorite if you guys want to just explore:

https://www.timejourney.ai/time/6903e39ac7a0142ce0ab4cc5 -- Golden Gate being constructed

https://www.timejourney.ai/time/690b76035362834122719553 -- Times Square in 1880

https://www.timejourney.ai/time/690dad930e74fc08393d9f15 -- Hiroshima in 1945

It's still a work in progress. Would appreciate it if anyone of you could check it out and give feedback. It works best on computer.
