A glitch is a short-lived fault in a system. We believe these errors happen only in algorithms. But is this really true? Would it be possible to see a glitch as any mistake in any system (around us)? In collaboration with Maloe Brinkman and Sanne Walvius we researched the topic of the glitch. The research led to an interactive analog installation. The installation took place in a dark space with two projectors on each side of the room. Two mirrors and four pieces of fabric were hanging from the ceiling. The projectors were beaming a red square grid, symbolizing a system. Each time a person interacted with the installation (by walking by) you saw the system changed or glitched.
