LONDON -- What would you rather look at on your commute to work? Adverts for a variety of upcoming books, films, products and theatre productions? Or just a hell of a lot of smiley cats? Correctly guessing that most people would go with option two, the Citizens Advertising Takeover Service (CATs) crowdfunded a dream to replace as many London underground ads as possible with feline-themed photos. Now, after raising £23,000 ($30,526) on Kickstarter, they've made that dream a reality. On Monday morning, commuters going through Clapham Common station were greeted by the following sight: The company behind CATs is a creative collective called Glimpse. They describe themselves on their site as "a group of friends who want to use creativity for good". "We tried to imagine a world where public space made you feel good," Glimpse founder James Turner was quoted as saying in a press release sent to Mashable. "We hope people will enjoy being in the station and maybe think a bit different about the world around them." The cat photos will be up around the station for two weeks, should you wish to visit.
