Deedit is a web-based app which encourages people to carry out small acts of kindness throughout the Edinburgh Festival, such as picking up litter, buying a sandwich for a stranger or giving directions.

Users are then encouraged to share their activity with a photo through the app.

The digital experience aims to tackle issues such as plastic pollution, litter and homelessness.

Deedit is part of a collaboration – named Project Mercury – between the Centre of Design Informatics and Tesco Bank to explore fintech, develop talent and foster innovation and creative thinking.

Project Mercury has seen university students and academics work in partnership with Tesco Bank’s digital and design-practice department to explore the possibilities of emerging digital technologies, such as blockchain. 

Grant Bourbousson, digital director at Tesco Bank, said: “Working with the university has provided a range of exciting development opportunities for our colleagues. 

“Participants in Project Mercury have explored ways in which we can harness developments in data technologies and how these could be used to help deliver better services for our customers. 

“This partnership demonstrates our commitment to talent development, innovation and the exploration of new and emerging technologies.”
