또 다른 세상과 마주하다, 시공간. 누구나 가끔은 ‘영화나 드라마 또는 게임이나 소설의 주인공이 나였으면 어떨까?’ 하는 상상을 하게 됩니다. 이야기 속 주인공이 되어 현실과 가상의 공간을 넘나들며 과거, 현재, 미래의 시간 여행을 할 수 있도록 하는 것이 시공간입니다. 시공간을 통해 여행을 즐기는 법! 하나. 여행자가 여행지에서 걸어 다니는 것. 둘. 여행지를 자세히 관찰하는 것. 셋. 추억을 기념하는 것. 현지에서 소비하는 것들이 모두 의미 있는 행위이며 그것이 다시 여행지에 도움이 되는 선순환의 서비스를 게임처럼 재미있게 만들고 싶었습니다. 여행에서 마주하게 될 또 다른 세상, 시공간을 넘나들며 이야기의 주인공이 되어보세요.
