Building on a foundation of interactive media arts, this paper explores the evolution from large-scale kinetic installations to a digital mental wellness platform, MindClay. The work was inspired by observing public interactions with the author's installations, which showed calming and motivational effects. A media arts museum was founded in part to compare the impacts of different installations on well-being. In collaboration with therapists, MindClay integrates evidence-based practices into a range of creative activities. The platform offers diverse therapeutic experiences in visual art, music, movement, and writing. This approach provides an engaging alternative to meditation apps, addressing the mental health needs of a broader audience. Through this convergence of art, science, and technology, MindClay aspires to make therapeutic creativity widely accessible.
