In order to offer the 30,000 participants of the We Run Seoul 10K 2011 event a personal goal and incentive for running, the idea was to develop a digital installation utilising a transparent display. A running shirt was on view behind the screen. Runners could have race T-shirts printed with their own messages and photos using innovative technology. A transparent touchscreen simulated how the customised design would look on an actual T-shirt. Furthermore, the slogan “Race of my life” became reality with a post-race printing service which allowed runners to have their personal records printed on a race T-shirt.
