Viewed as a whole, modern Indonesian art seems like a mosaic on the move. In this mosaic is then reflected the spirit of the age, which at the same time relates to the life of the Indonesian people in general. Indonesian artists today look upon themselves as a member of a bigger family, the family of man. They know that they have received something from this big family, and whenever they create, they know that they not only contribute something to the artistic wealth of their nation, but also to the artistic wealth of man. - Ahmad Sadali As one the few Indonesian modern artists who made distinctive contributions to the development of abstract art in Indonesia, Fadjar Sidik started his abstract experimentations in the late 1950s and was fully immersed in developing his own visual vocabulary of abstract forms and compositions from the 1960s onwards. He began to explore spatial relationships, akin to how technology enabled us to see and experience a kaleidoscope of world cultures. Dinamika Pelangi (Dynamics of Rainbow) is a work that bridges the artist's 1960s architectonic forms with a later, extremely vibrant and rare rainbow spectrum of hues. In the work, nature is conceived of as a unified whole. The sky encounters the sea, seen in the symbol of the moon or sun atop a form that looks to be in flight. A closer look reveals an unmistakable fish form at the bottom of the form.

Fadjar Sidik was born in Surabaya in 1930. He studied at ASRI Yogyakarta in 1954 and learned painting from Hendra Gunawan and Sudarso (1952) at Sanggar Pelukis Rakyat. He lived in Bali from 1957 - 1961. He received art awards as Contemporary Painter from the Indonesian Government in 1971 and from the Government of Yogyakarta.
