LtCmdr_Bill,
Welcome to the forums . . . . I just did a random searh on the internet to find that picture. I think it was 'dome structure' or something like that. Right now I did another google search to see if I could find it for you but I think I took the last picture beause it's gone . .
if you google for futuristic dome or dome structure I am sure you would come accross it.
