Since the National Institute for Mathematical Sciences (NIMS) presented a very successful NIMS-IMAGINARY exhibition in collaboration with MFO in ICM 2014, we have been operating a permanent IMAGINARY exhibition in Korea. In this talk, we will go through the achievements we have made during the last 2 years. In particular, as a government-funded research institute, we will share our experiences on how we have used relevant community resources, developed mathematics communication networks and overcame practical obstacles.
