Even though some ideas aren't very practical for everyday usage, they are still pretty cool nonetheless. One such project is the one where a team from Framework turned an actual school bus into a virtual Mars ride. It's a pretty intense project. They have computer screens that switch from clear to opaque, so that the windows of the bus can be windows as well as computer screens. Then the mapped the surface of Mars to the city streets. Then they made the simulation react to bumps and turns. Sounds really expensive, but the idea is a good one. Watch the video above to see the whole thing - the look on the kids faces are priceless.
