This paper aims to elaborate on the question of how digital interactions may enable action leading to sustainable actions.  In the first section, we introduce the background of our experiment: eco-design practices that may engender human behaviour shifts in interior spaces for addressing questions of comfort and sustainability. In the second part, we describe the experiment, how it was designed and why it was designed. In the third section, we provide our theoretical foundations by elaborating on the three main research fields the experiment touches: eco-art as a teaching agent, digital eco-art as companionship for sustaining eco-beneficial human-machine interaction, and eco-art as a way to address climate anxiety in humans and tackle the Anthropocene. In the concluding section, we elaborate on the results of the experiment by reflecting on a series of future questions and issues. Is interactive digital art a promising method for a call to action?  What are the potential downfalls of studies on long-term behaviour?  We also elaborate on the promises that this type of technological motivation for action involves. We open the possibility of future research by asking if interactive digital art can push eco-art practices beyond awareness-raising and into the realm of action.
