The Porsche 919 Hybrid racing car is so stable that even at high speeds, it looks as if it's barely moving. In order to invite fans to see it for real at the 24h Mans race, Porsche sent them with a direct mailing with a virtual surprise. The mail could be folded into a box showing a picture of the car. But thanks to a QR code and your smartphone, the box could be transformed into a small theater showing the Porsche 919 speeding along the road - while apparently standing still.
