Now this is fun. Developed by the team at Benrik, Situationist is an iPhone app that ‘makes your everyday life more thrilling and unpredictable’. How? Simple: ‘It alerts members to each other’s proximity and gets them to interact in random situations. These situations vary from the friendly (“Compliment me on my haircut”) to the subversive (“Help me rouse everyone into revolutionary fervour”). The point of it all, of course, is to interact with strangers. Clever? Yes. Frightening. Perhaps.
