Some pieces on show are less explicitly connected to the concept of light and have been chosen to address broader conceptual themes of perception and sensory awareness. Wuhan-born installation and video artist Feng Chen’s ongoing project The Darker Side of Light is represented in Lumen by his video piece, Moment by Moment. In a corridor of galleries between large display rooms, Moment by Moment seems to offer an opportunity to recalibrate our senses. On one side, the screen shows a virtual metronome, accompanied by the device’s rhythmic ticking. On the other, an identical, physical metronome sways along. Tricked into thinking the digital and tangible are keeping time in unison, and looking side to side to keep track of them, the viewer is lulled into a false sense of security. However, every so often, the video metronome falls out of synch, disorienting the mind as the viewer tries to right themselves, and find the right beat again. In a world of many realities, only complicated by our dual physical and digital lives, Moment by Moment challenges our sense of objective reality, asking to what extent we can truly rely on our senses.
