Flora Luma is a plant-controlled installation, developed by the authors. It utilises bioelectrical signals to drive color-animation of self-illuminating objects. Electrical signaling constitutes a part of plant vocabulary, employed for intra- and interspecies communication. Recent findings ascertain plants to be much more perceptive of their environment, than previously thought [2,5]. Terms like plant behaviour and plant intelligence are entering scholarly discourse and have been the subject of both major articles in respected media [3,8] and artistic exploration [10]. Yet, the public is largely unaware of the richness of plant life and communication. Flora Luma is designed to provide an insight into the inner workings of plant life, serving as a mediating device allowing the spectator to directly interact with the plant and receive visible real-time feed-back. Plant and human become hybrid agents jointly creating unique artistic reality. The installation highlights the reciprocal relationship and participatory nature between vegetal and human space.
