Five gifs for an activation campaign for De Lijn, a Belgian public transport company. While on the bus or tram, you have your hands free, so you can do anything. To emphasize this, De Lijn put discount stickers on the inside of windows in over 600 busses and trams. When you made a picture of a 75% off sticker with for example a shoe shop in the background, you could win 75% off in that shoe shop. Hurray! And as you can see, your dog would be really happy too.
