Working primarily with 3D software, Fu creates scenes of experimental abstraction that translate the concept of liminality into the digital experience. The word liminal is often used to discuss the sublime within digital space and the VR experience, conjuring up notions of time, space, and perception, and echoing the experience of the sublime in nature. The word is borrowed from the field of anthropology; anthropologist Victor Turner described as ‘the quality of ambiguity or disorientation that occurs in the middle stage of a rite of passage’, which ‘serves not only to identify the importance of in-between periods, but also to understand the human reactions to liminal experiences.’ Fu’s work draws parallels between the physical, virtual, metaphysical, and multi-dimensional, setting the viewer in a liminal space at the threshold of what Turner called ‘a period of scrutiny for central values and axioms.’
