The Brief
Wonderhood Studios approached us with a brief to develop a bespoke Chrome browser extension to be available to download as part of the “Lunch Break” advertising campaign they delivered for Branston Pickle.
The campaign centred on the idea of encouraging workers to take back their lunch breaks and “Stop work eating your lunch!”.
Once installed the plugin needed to be configurable so that it could prevent users from using their computer during their lunch break - their screen is taken over by a giant animated sandwich and their cursor becomes the iconic Branston Pickle jar - and therefore enjoy a tasty cheese and pickle sandwich (other sandwiches are available) and some well-earned time away from their desk.

What we did
We developed the Google Chrome Extension in a matter of weeks with regular meetings with the team at Wonderhood. The project presented several challenges as the Chrome Extension needed to takeover any number of tabs the user might have open at that time, so an event needed to be broadcast so that all tabs could be taken over at the same time, and also relinquished when the lunch break ended. The Chrome Extension also used Google Chrome’s internal Storage APIs in order to retain its configuration options.
The Chrome Extension also included a feature where it would send the user notifications as a countdown to the start of their configured lunch hour. These were sent using native Chrome notifications but needed some advanced logic to skip or reset the cycle of countdown notifications if the user adjusted their lunch hour and brought the start time forward or moved it back.
