Virtual Tours? Thread

Does anyone know of any software that would be a first person virtual tour?Say like a dvd where you take a tour of The Smithsonian like an fps game,only just a tour?I would be interested to know if there is anything like this,and where it might be purchased.Thanks in advance!

Googling around it seems limited to certain locations and college campuses.

Yeah,it does.But I'm not in college.I'm a grandmother.You are right though.It is limited.I do thank you for your help,though.

I'm sure Virtual tours will become far more common in the future. Just doesn't seem to be a big thing on peoples minds right now. Maybe I should figure out how to make these things and make a business out of it. :p

I used to have a disk back in the 90's with a virtual tour of Ripley's Believe It Or Not Museum.Nothing looked too real of course,but it was great.That is until somebody swiped it.Oh,well.
Can you imagine a first person tour of something like the Louvre in Paris?Or Madame Tussaud's Wax Museum in London?
Or better yet,how about starting off with the main street of a small town,anywhere in the world.Some small shops,maybe a post office and a church,a few houses?Something where you could interact with the fictional people,perhaps visit a "friend" in their home?
I'm not talking about the Sims,or horror games.I'm talking about being able to freely move around and explore.No zombies or monsters,just good clean exploring suitable for all ages.
While I realize something like this would cost a lot to make,not to mention being time consuming,something like these ideas just might be worth the effort.
Well,sorry for being so long winded.If you decide to try anything like this,I would wish you the VERY best of luck.Also,the credit should go to all who would help in the making of something like this.So if you are REALLY interested,GO FOR IT! Have a good one!
