Gegerboyo is a group of young artists founded in Yogyakarta in 2017. The members of this group are Anjali Nayenggita, Enka Komariah, Prihatmoko Moki, and Vendy Metodhos. Gegerboyo comes from the name of a hill that looks like the back (Javanese: geger) of a crocodile (Javanese: boyo) at south part of Mount Merapi.

This group of young artists is interested in mythology and mystical sites that are sacred in Java. Their works in the form of mural and installation were recently exhibited at Setouchi Triennale, Japan 2022. Their installation works at ARTJOG was based on research on a pilgrimage site which local community named Gunung Hargo Gumilang or Gunung Tutup in Ponjong, Gunung Kidul, Yogyakarta. Their interest in this trail was sparked by a story about the role of a figure in Indonesian politics named Sukino Suprobo. Mr. Kino is known to have supernatural power and healing power, earned the nickname "a man who cares for a mountain" and during his lifetime was close to the figure of President Soekarno. This figure is also a promoter for traditional Javanese art. This memorial is sacred because apart from Mr. Kino, there is also a grave of Eyang Mangunkusumo, a direct descendant of Mangkunegara I or Prince Samber Nyawa who was known to be anti-colonial and a National Hero.

This installation works tries to bring back the forms, content and essence of the ruins of Gunung Tutup which was built on four principles, namely socialism (gotong-royong), nationalism, spiritualism and culture. This site is also known as the site of diversity or the site of Pancasila ideology because it was formed from a syncretic mixture of elements of Hinduism, Islamic background, Javanese culture and others. Gunung Tutup has also been interpreted by local community as "something that is covered up". The visual aesthetic motif developed by Gegerboyo group is characterized by "obar-abir", "tumpuk-tundung" and "uba rampe", all of which refer to the richness and unity of various elements in the ritual tradition.
