Realtime Unreal addresses the fusion of physical and digital space. The installation employs 2 stereoscopic projections on a double-sided projection screen and game engine software customized by the artists, capturing visitors in the physical space and displaying them in an imaginary world. The virtual world seems to occupy physical space like a sculpture in the museum, an alternate reality floating in midair. Walking around the virtual world alters its viewpoint, reveals impossible perspectives and simultaneous occurrences, and disrupts its architecture. Realtime Unreal challenges visitors to bridge the gap between what their eyes perceive and what their minds believe is unreal.
