What is Tetragram?
- It's like a magical camera, through the camera you will see a digital picture posted on a real object such as a wall or table.
- Not just see, everyone can post their own pictures to real walls, as long as there is a QR code printed on the wall.
- The picture exists permanently, you can tell friends to see it anytime on the place with Tetragram app.
