Three people have spent the past three years building a video game that works like a pop-up book.

Launching today for iPad, Tengami is a beautiful adventure that looks like a cross between a children's pop-up book and Japanese origami. And that theme doesn’t just extend to the way the game looks, but also how it feels — you'll use the touchscreen to push and pull the world around, manipulating it just like you would a physical book. "A pop-up book is essentially a toy book," says co-developer Jennifer Schneidereit, "and we wondered what would happen if we translated that into a video game."
