Mattel has a series of iPad games called Apptivity. They’re intended for use with figures, which you place directly on the iPad surface to control the game.
Cultures across the planet have been making toys for thousands of years. Lots of us grew up playing with toy cars.
What do you do with a toy car? You drive it. You drive it on the floor, on a playmat, between toy buildings, on tracks, etc.
With Apptivity, you can now also drive it on a magic window that goes anywhere. Consider that for a minute.
This is the future. We are living in the future.
