The main structure of the self-checkout counter was built out of old pallets and sturdy recycling cardboard. / CC BY Niklas Roy & Kati Hyyppä

The laptop was built in a cardboard case above the scanning surface. For decoration we found quite realistic looking 'metal' foil. / CC BY Niklas Roy & Kati Hyyppä

The barcode reader, the receipt printer and an Arduino were connected via USB to the laptop. The Arduino was reading the Start button. On the right is a also small speaker to play atmospheric supermarket announcements. / CC BY Niklas Roy & Kati Hyyppä

For light effects a separate Arduino board was added, which controlled individually addressable RGB LED strips. / CC BY Niklas Roy & Kati Hyyppä

The product selection at Bonprix. The cheaper products included food items and the luxury section expensive accessories. A sewer plunger was also available. For the final game we left out the cake, lemon and the clothes pins. / CC BY Niklas Roy & Kati Hyyppä

In the beginning of the game the products were neatly placed in a shopping basket. / CC BY Niklas Roy & Kati Hyyppä

The game was started with the yellow button below the screen. / CC BY Niklas Roy & Kati Hyyppä

The player had to scan the product shown on the screen. Here canned spaghetti is being scanned. / CC BY Niklas Roy & Kati Hyyppä

The luxury items were more expensive und yielded thus more points. The progress bar below the product shows the remaining time. / CC BY Niklas Roy & Kati Hyyppä

When the 90 seconds time limit was over, a score-receipt was printed out. A small text below the score also showed the daily high score for comparison. / CC BY Niklas Roy & Kati Hyyppä

The thermal printer was inside a cardboard box. / CC BY Niklas Roy & Kati Hyyppä

We needed quite a few test prints to achieve the desired receipt layout for Bonprix. / CC BY Niklas Roy & Kati Hyyppä

During the high speed shopping the products ended up all over the place, which made scanning amusingly messy. / CC BY Niklas Roy & Kati Hyyppä

It seemed like it was fun to play as well as to watch others play. / CC BY Niklas Roy & Kati Hyyppä

We also found some 50% discount stickers, which we gave to the players. / CC BY Niklas Roy & Kati Hyyppä

'Baguette du jour' also got some extra 50% discount stickers, as it suffered from rough gameplay and had to be repaired couple of times. / CC BY Niklas Roy & Kati Hyyppä
