The picture shows a woman sitting on a couch and reading the ista heating bill. She has long blonde hair and is wearing black glasses. Her top is a blue shirt and she is wearing brown trousers. While she holds the heating bill in her left hand, her right hand rests on her chin. She looks directly into the camera. The beige couch on which she is sitting stretches across the entire lower third of the picture and has a white blanket draped over the back on the left with a yellow cushion leaning against it. In the background are various pieces of furniture that suggest a living room: A floor lamp and a shelf can be seen on the right, and in the centre an open two-part door leading into another room with bookshelves.

The picture shows a row of narrow but tall terraced houses. The terraced houses have alternating grey and white façades. On the left you can see a house with a white façade and on the far right a house with a grey façade. They are also always built at different heights, so that there are never two houses of the same height next to each other. All the houses have a large square window front in the upper half, consisting of 30 small square windows. The window front of the fourth house from the right is the only one covered by a blind. All of the houses have four individual windows under the fronts, with two on the left and two on the right below each other. Above the houses you can see the almost completely cloudless blue sky. In the foreground in front of the houses you can see a lawn with many bushes and a total of four trees, three of which can be seen on the left at the edge of the picture and one tree on the right.

The picture shows a bird's eye view of an urban intersection. There are several wide streets that meet in the centre of the picture and form a complex network of traffic routes. Numerous curved, bright blue lines run across these streets, symbolising the flow of data or information exchange. These lines start from different points and concentrate in the centre of the intersection, creating a radial pattern. At the bottom of the picture, several moving cars can be seen travelling along the road. On the left-hand side of the picture is a building with a car park where several cars are parked. On the right-hand side of the picture, tall, modern office buildings with large window fronts are visible, emphasising the urban environment. The blue lines that dominate the image convey a dynamic sense of connectivity and technology, while the underlying urban infrastructure provides the physical basis for this digital exchange.
