Viewpoint binoculars on a turret. You strap yourself into the seat and rotate it with joysticks. When facing the ground, you see through Earth as if it was transparent via Google Maps/Street view.
A fun way to explore the world.
Get a better feel for the world's geography.
Can be turned into a vending machine where people pay to play with the machine.
A rotating seat with powerful binoculars. You strap yourself into the seat and use joysticks to rotate in any direction.
The viewfinder is digital. It's connected to powerful binoculars that can zoom all the way to telescope level resolution.
As soon as your direction tilts below horizon, the image switches to google earth and street view option. You see the place that would be in your line of sight if the Earth was transparent.
Example: You are in Geece, looking at Google street view in New York.
As soon as you tilt the seat back up, to face a direction above horizon, the view switches to binoculars. When you're facing the sky, the view switches to a powerful telescope.
The binoculars and telescope are mounted on the gyrosopic/rotating turret.
The idea was inspired by this one. Specifically it's a solution to the problem mentioned in J. Nikola's comment.
